Hi aspensbubble ,  I also had that vibration happening in my head which moved to my legs it took about 5 months post removal before it went away it is very scary !!  i hope you start feeling better soon

I looked up throbbing nerve and found another girl posted a blog 82 days ago about pseudotumor cerebri and I actually wrote to her but never looked into what that was and that totally fits what is wrong with me. If anyone is interested here is some imformation about it.I will find out on Jan. 6th. Thanks for your responses!! Idiopathic intracranial hypertension (IIH), sometimes called by the older names benign intracranial hypertension (BIH) or pseudotumor cerebri (PTC), is a neurological disorder that is characterized by an increased intracranial pressure (pressure around the brain) in the absence of a tumor or other diseases. The main symptoms are headache, nausea and vomiting as well as pulsatile tinnitus (buzzing in the ears), double vision and visual symptoms. If untreated, it may lead to vision loss due to associated swelling of the optic disc in the eye.[1] IIH is diagnosed with a brain scan (to rule out other causes) and a lumbar puncture; lumbar puncture may also provide temporary and sometimes permanent relief from the symptoms. Some respond to medication (with the drug acetazolamide), but others require surgery to relieve the pressure. The condition may occur in all age groups, but is most common in young women, especially those suffering from obesity.[1] Contents [hide] 1 Signs and symptoms 2 Causes 3 Mechanism 4 Diagnosis 5 Classification 6 Treatment 6.1 Lumbar puncture 6.2 Medication 6.3 Surgery 7 Prognosis 8 Epidemiology 9 History 10 References 11 External links [edit] Signs and symptoms The most common symptom of IIH is headache, which occurs in almost all (92–94%) cases. It is characteristically worse in the morning, generalized in character and throbbing in nature. It may be associated with nausea and vomiting. The headache can be made worse by any activity that further increases the intracranial pressure, such as coughing and sneezing. The pain may also be experienced in the neck and shoulders. Many have pulsatile tinnitus, a whooshing sensation in one or both ears (64–87%). Various other symptoms, such as numbness of the extremities, generalized weakness, loss of smell, and incoordination, are reported more rarely; none are specific for IIH.[1] In children, numerous nonspecific signs and symptoms may be present.[2] The increased pressure leads to compression and traction of the cranial nerves, a group of nerves that arise from the brain stem and supply the face and neck. Most commonly, the abducens nerve (sixth nerve) is involved. This nerve supplies the muscles that pull the eye outward. Those with sixth nerve palsy therefore experience horizontal double vision which is worse when looking towards the affected side. More rarely, the oculomotor nerve and trochlear nerve (third and fourth nerve palsy, respectively) are affected; both play a role in eye movements.[2][3] The facial nerve (seventh cranial nerve) is affected rarely–the result is weakness of all face muscles on one side of the face.[1] The increased pressure leads to papilledema, which is swelling of the optic disc, the spot where the optic nerve enters the eyeball. This occurs in practically all cases of IIH, but not everyone experiences symptoms from this. Those who do experience symptoms typically report "transient visual obscurations," episodes of difficulty seeing that occur in both eyes but not necessarily at the same time. Long-term untreated papilledema leads to visual loss, initially in the periphery but progressively towards the center of vision.[1][4] Physical examination of the nervous system is typically normal apart from the presence of papilledema, which is seen on examination of the eye with a small camera called an ophthalmoscope or in more detail with a fundus camera. If there are cranial nerve abnormalities, these may be noticed on eye examination in the form of a squint (third, fourth and sixth) or as facial nerve palsy. If the papilledema has been longstanding, visual fields may be constricted and visual acuity may be decreased. Visual field testing by automated (Humphrey) perimetry is recommended as other methods of testing may be less accurate. Longstanding papilledema leads to optic atrophy, in which the disc looks pale and visual loss tends to be advanced.[1][4] [edit] Causes "Idiopathic" means "without an underlying cause". Therefore, IIH can only be diagnosed if there is no alternative explanation for the symptoms. Intracranial pressure may be increased due to various other causes. This may be medication, such as high-dose vitamin A derivatives (e.g. for acne), long-term tetracycline antibiotics (for a variety of skin conditions) and the oral contraceptive. There are numerous other diseases, mostly rare conditions, that may lead to intracranial hypertension. If there is an underlying cause, the condition is termed "secondary intracranial hypertension".[1] Common secondary causes of intracranial hypertension include obstructive sleep apnea (a sleep-related breathing disorder), systemic lupus erythematosis (SLE), chronic kidney disease and Behçet's disease.[4] [edit] Mechanism The cause of IIH is not known. The Monro-Kellie rule states that the intracranial pressure (literally: pressure inside the skull) is determined by the amount of brain tissue, cerebrospinal fluid (CSF) and blood inside the bony vault. Three theories therefore exist as to why the pressure might be raised in IIH: an excess of CSF production, increased volume of blood or brain tissue, or obstruction of the veins that drain blood from the brain.[1] The first theory, that of increased production of cerebrospinal fluid, was proposed in early descriptions of the disease. However, there is no experimental data that supports a role for this process in IIH.[1] A second theory posits that either increased blood flow to the brain or increase in the brain tissue itself may result in the raised pressure. Little evidence has accumulated to support the suggestion that increased blood flow plays a role, but both biopsy samples and various types of brain scans have shown an increased water content of the brain tissue. It remains unclear why this might be the case.[1] A third theory suggests that blood flow from the brain may be impaired or congested. Only in a small proportion of patients has underlying narrowing of the cerebral sinuses or veins been demonstrated. Congestion of venous blood may result from a generally increased venous pressure, which has been linked to obesity.[1][4] [edit] Diagnosis The diagnosis may be suspected on the basis of the history and examination. To confirm the diagnosis, as well as excluding alternative causes, several investigations are required; more investigations may be performed if the history is not typical or the patient is more likely to have an alternative problem: children, men, the elderly, or women who are not overweight.[3] Neuroimaging, usually with computed tomography (CT/CAT) or magnetic resonance imaging (MRI), rules out mass lesions. In IIH these scans may be normal, although small or slit-like ventricles and "empty sella sign" (flattening of the pituitary gland due to increased pressure) may be seen. An MR venogram is also performed in all cases (or according to some experts only in atypical cases[3]) to exclude the possibility of venous obstruction or cerebral venous sinus thrombosis.[1][2][3] Lumbar puncture is performed to measure the opening pressure, as well as to obtain cerebrospinal fluid (CSF) to exclude alternative diagnoses. If the opening pressure is increased, CSF may be removed for relief (see below).[3] The CSF is examined for abnormal cells, glucose and protein levels; in IIH, all are within normal limits.[3] Occasionally, the pressure measurement may be normal despite very suggestive symptoms. This may be attributable to the fact that CSF pressure may fluctuate over the course of the day. If the suspicion remains high, it may be necessary to perform more long-term monitoring of the ICP by a pressure catheter.[3] [edit] Classification The original criteria for IIH were described by Dandy in 1937.[5] Dandy criteria[5] 1 Signs & symptoms of increased ICP – CSF pressure >25 cmH2O 2 No localizing signs with the exception of abducens nerve palsy 3 Normal CSF composition 4 Normal to small (slit) ventricles on imaging with no intracranial mass They were modified by Smith in 1985 to become the "modified Dandy criteria". Smith included the use of more advanced imaging: Dandy had required ventriculography, but Smith replaced this with computed tomography.[6] In a 2001 paper, Digre and Corbett amended Dandy's criteria further. They added the requirement that the patient is awake and alert, as coma precludes adequate neurological assessment, and require exclusion of venous sinus thrombosis as an underlying cause. Furthermore, they add the requirement that no other cause for the raised ICP is found.[1][4][7] Modified Dandy criteria[7] 1 Symptoms of raised intracranial pressure (headache, nausea, vomiting, transient visual obscurations, or papilledema) 2 No localizing signs with the exception of abducens (sixth) nerve palsy 3 The patient is awake and alert 4 Normal CT/MRI findings without evidence of thrombosis 5 LP opening pressure of >25 cmH2O and normal biochemical and cytological composition of CSF 6 No other explanation for the raised intracranial pressure In a 2002 review, Friedman and Jacobson propose an alternative set of criteria, derived from Smith's. These require the absence of symptoms that could not be explained by a diagnosis of IIH, but do not require the actual presence of any symptoms (such as headache) attributable to IIH. These criteria also require that the lumbar puncture is performed with patient lying sideways, as a lumbar puncture performed in the upright sitting position can lead to artificially high pressure measurements. Friedman and Jacobson also do not insist on MR venography for every patient; rather, this is only required in atypical cases (see "diagnosis", above).[3] [edit] Treatment The primary goal in treatment of IIH is the prevention of visual loss and blindness, as well as symptom control.[4] IIH is treated mainly through the attempted reduction of CSF pressure and, where applicable, weight loss. IIH may resolve after initial treatment, may go into spontaneous remission (although it can still relapse at a later stage), or may continue chronically.[1][3] [edit] Lumbar puncture A lumbar puncture in progress. A large area on the back has been washed with an iodine-based disinfectant leaving brown colouration. In this image the patient is seated upright, which can make the procedure easier to perform but makes any measurement of the opening pressure less reliable. The first step in symptom control is drainage of cerebrospinal fluid by lumbar puncture. If necessary, this may be performed at the same time as a "diagnostic" LP. In some cases, this is sufficient to control the symptoms, and no further treatment is needed.[2][4] The procedure can be repeated if necessary, but this is generally taken as a cue that additional treatments may be required to control the symptoms and preserve vision; repeated LPs are regarded as unpleasant by patients.[1][2] Repeated LPs are sometimes needed to control the ICP urgently if vision deteriorates rapidly.[4] [edit] Medication The best studied medical treatment is acetazolamide (Diamox), which acts by inhibiting the enzyme carbonic anhydrase and reduces CSF production by 6–57%. It can cause the symptoms of hypokalemia (low blood potassium levels), which include muscle weakness and tingling in the fingers. Acetazolamide cannot be used in pregnancy, as it has shown to cause embryonic abnormalities in animal studies, and in humans has been shown to cause metabolic acidosis as well as disruptions in the blood electrolyte levels in the newborn. The diuretic furosemide is sometimes used if acetazolamide is not tolerated, but this has little effect on the ICP.[1][4] Various analgesics (painkillers) may be used in controlling the headache. In addition to conventional agents such as paracetamol, a low dose of the antidepressant amitriptyline as well as the anticonvulsant topiramate have shown some additional benefit for pain relief.[4] The use of steroids to reduce the ICP is controversial; they may be used in severe papilledema, but otherwise their use is discouraged.[1] [edit] Surgery Two main surgical procedures exist in the treatment of IIH: optic nerve sheath decompression and fenestration and shunting. Surgery would normally only be offered if medical therapy is either unsuccessful or not tolerated.[2][4] The choice between these two procedures depends on the predominant problem in IIH. Neither procedure is perfect: both may cause significant complications, and both may eventually fail in controlling the symptoms. There are no randomized controlled trials to guide the decision as to which procedure is best.[4] Optic nerve sheath fenestration is an ophthalmological operation that involves the making of an incision in the connective tissue lining of the optic nerve in its portion behind the eye. It is not entirely clear how it protects the eye from the raised pressure, but it may be the result of either diversion of the CSF into the orbit or the creation of an area of scar tissue that lowers the pressure.[4] The effects on the intracranial pressure itself are more modest. Moreover, the procedure may lead to significant complications, including blindness in 1–2%.[1] The procedure is therefore recommended mainly in those who have limited headache symptoms but significant papilledema or threatened vision, or in those who have undergone unsuccessful treatment with a shunt or have a contraindication for shunt surgery.[4] Shunt surgery, usually performed by neurosurgeons, involves the creation of a conduit by which CSF can be drained into another body cavity. The initial procedure is usually a lumboperitoneal (LP) shunt, which connects the subarachnoid space in the lumbar spine with the peritoneal cavity. Generally, a pressure valve is included in the circuit to avoid excessive drainage when the patient is erect and therefore has a relatively high ICP. LP shunting provides long-term relief in about half the cases; others require revision of the shunt, often on more than one occasion—usually due to shunt obstruction. If the lumboperitoneal shunt needs repeated revisions, a ventriculoatrial or ventriculoperitoneal shunt may be considered. These shunts are inserted in one of the lateral ventricles of the brain, usually by stereotactic surgery, and then connected either to the right atrium of the heart or the peritoneal cavity, respectively.[1][4] Given the reduced need for revisions in ventricular shunts, it is possible that this procedure will become the first-line type of shunt treatment.[1] In cases of severe obesity, gastric bypass surgery has been shown to lead to a marked improvement in symptoms.[1][8] [edit] Prognosis It is not known what percentage of people with IIH will remit spontaneously, and what percentage will develop chronic disease.[4] IIH does not normally affect life expectancy. The major complications from IIH arise from untreated or treatment-resistant papilledema. In various case series, the long-term risk of ones vision being significantly affected by IIH is reported to lie anywhere between 10 and 25%.[1][4] [edit] Epidemiology The incidence of IIH is strongly determined by sex and body weight. The figures in females are in women between 20 and 45 years old.[1] On average, IIH occurs in about 1 per 100,000 people, and can occur in children and adults. The median age at diagnosis is 30. IIH occurs predominantly in women, especially in the ages 20–45, who are four to eight times more likely than men to be affected. Overweight and obesity strongly predispose a person to IIH: women who are more than ten percent over their ideal body weight are thirteen times more likely to develop IIH, and this figure goes up to nineteen times in women who are more than twenty percent over their ideal body weight. In men this relationship also exists, but the increase is only fivefold in those over 20% above their ideal body weight.[1] Despite several reports of IIH in families, there is no known genetic cause for IIH. People from all ethnicities may develop IIH.[1] In children, there is no difference in incidence between males and females.[2] From national hospital admission databases it appears that the need for neurosurgical intervention for IIH has increased markedly over the period between 1988 and 2002. This has been attributed at least in part to the rising prevalence of obesity,[9] although some of this increase may be explained by the increased popularity of shunting over optic nerve sheath fenestration.[4] [edit] History The first report of IIH was by the German physician Heinrich Quincke, who described it in 1893 under the name "serous meningitis".[10] The term "pseudotumor cerebri" was introduced in 1904 by his compatriot Max Nonne.[11] Numerous other cases appeared in the literature subsequently; in many cases, the raised intracranial pressure may actually have resulted from underlying conditions.[12] For instance, the "otitic hydrocephalus" reported by London neurologist Sir Charles Symonds may have resulted from venous sinus thrombosis caused by middle ear infection.[12][13] Diagnostic criteria for IIH were developed in 1937 by the Baltimore neurosurgeon Walter Dandy; Dandy also introduced subtemporal decompressive surgery in the treatment of the condition.[5][12] The terms "benign" and "pseudotumor" derive from the fact that increased intracranial pressure may be associated with brain tumors. Those patients in whom no tumour was found were therefore diagnosed with "pseudotumor cerebri" (a disease mimicking a brain tumor). The disease was renamed "benign intracranial hypertension" in 1955 to distinguish it from intracranial hypertension due to life-threatening diseases (such as cancer);[14] however, this was also felt to be misleading because any disease that can blind someone should not be thought of as benign, and the name was therefore revised in 1989 to "idiopathic (of no identifiable cause) intracranial hypertension".[15][16] Shunt surgery was introduced in 1949; initially, ventriculoperitoneal shunts were used. In 1971, good results were reported with lumboperitoneal shunting. Negative reports on shunting in the 1980s led to a brief period (1988–1993) during which optic nerve fenestration (which had initially been described in an unrelated condition in 1871) was more popular. Since then, shunting is recommended predominantly, with occasional exceptions.[1][4] [
