Hi
Welcome to the forum!
More than the pain clinic, you should consult a gastroenterologist. You could be suffering from Celiac Disease/Ulcerative Colitis/Irritable Bowel Syndrome/ Crohn’s disease. All these result in tender abdomen, loose stool or loose stools alternating with constipation, abdominal distention and bloating, cramps etc. A number of times a gastroenterologist is able to diagnose these conditions by clinical examination and detailed medical history. Or he will run blood to rule out anemia, stool test to look for white blood cells, or may ask for sigmoidoscopy, colonoscopy etc to diagnose ulcerative colitis. Braium meal and follow through, endoscopy etc are done to rule out GERD, Crohn’s disease etc. Irritable bowel syndrome is diagnosed by elimination of other causes. Gluten is a complex protein present in four main grains---wheat, rye, barley and oats. If you have gluten intolerance, then you probably have celiac disease or Non Celiac gluten sensitivity. There are blood tests called celiac test to detect gluten intolerance.
It is difficult to comment beyond this at this stage. Please let me know if there is any thing else and do keep me posted. Take care!
have you heard of celiac disease? I think alot of your symptoms go along with celiacs. i was tested for that a few months ago. my test was negative, like you i have been ill for about 5 years, with no diagnosis. but ive heard people with celiacs disease say their stomach would swell up and they looked pregnant after they ate. if you have celiacs you cant eat wheat, oat, barley, and other grains. basically no bread. i did alot of research on it when the doctor wanted to test me for it, you could research it and see if it sounds like you! hope this helps!!
