It is possible to have migraine all the time but it is also possible for anxiety to affect your migraine so it feels like it is all the time, what we need to do here is to find the difference! Recording all of this can be quite a task but it will be evidence that will help a decent Neuro figure out what is going on! You need to record the off balance sensations and any other symptom too. Recently I got a product of Migravent. You can consult your doctor before taking caz you are going through treatment. Get well soon.
There is a condition called Vertigo. It is a sensation of dizziness and world spinning around you. It also gives you sensation of pressure in your head. It is caused by little crystals moving in your inner ear. There is no cure, because it is not an illness. There is an exercise that you can do to help you move the crystals back: Lay on oyur side with lower arm in front and up above your head. Tilt your head up and hold that position for 5 to 10 minutes. Repeat on the other side.
