This may give you some leads for some further reading and research.

It would appear that you are describing the position of the ileocecal sphincter (valve). This valve is at the junction of the large and small intestines. It consists of a muscular valve which under certain circumstances can malfunction by going into spasm, either closed or open; you would feel a hardish lump halfway in a line drawn from the navel to the hip bone.

The other signs of ileocecal valve syndrome are shared with many other digestive problems, and include the following:

Dizziness
Dark circles under the eyes
Fatigue
Bad breath
General malaise
Headache
Low back pain
Nausea
Pain around the heart
Palpitations
Sinus problems
Shoulder pain
Sudden thirst
Ringing in the ears
Water retention

It is very similar to IBS. Bad breath is a good pointer because the lungs take over some of the detoxification work of the bowels and expel toxic gases.

It can be treated by a chiropractic who would concentrate on vertebras C4-C7, T10-L2, the sacrum as well as the cranial. Acupuncture on the kidney meridian can be useful as kidney function is linked to ileocecal sphincter function.

Massage of the ileocecal valve using techniques known as , the wheel technique, the intestinal lift technique, and the reflex techniques, can be used to relax the ileocecal valve.

Nutritional supplements may help, such as digestive enzymes, probiotics, betain, HCL, minerals (e.g., magnesium, calcium, zinc, and copper) and nutrients (e.g., beta carotene, vitamin C, and other antioxidants.

Herbals would include such things as peppermint, chamomile, fennel, and liquorice.

Aerobic exercise such as walking, jogging, cycling, swimming, and/or rope jumping is good because it has a significant effect on the gastrointestinal and lymphatic systems.

Also helpful may be lifestyle changes to reduce stress and dietary changes (e.g., temporarily reducing roughage and spicy foods). Cutting out nicotine and alcohol use is going to help.

This condition can be triggered by an emotional upset and doctors can prescribe anti-anxiety and anti-depressant drugs. It’s better to try and reduce stress yourself by trying to more relaxed, not easy when you’re worried about your health.
