I began having diarrhea 7 months ago after eating a fast food chicken sandwich. 3 sets of stool samples (1st 2 weeks after onset); endoscopy, colonoscopy, 3 abd/pelvic CTs, and CT enteroclysis, all neg. Began having deep RLQ pain a month after onset of diarrhea. Is constant, aching/burning, waxes/wanes. Can now localize pain - just right of navel; feels like a rock, elicits considerable pain with palpation, sends burning type pain into abd, rt. groin, rt. thigh when push down on it. Nausea increasing, esp. after eating. Considerable wt. loss - now avg. 3-4 lb./mo.; 6 pant sizes in 6-7 months. Had consult with dietitian, increased calorie intake, still lost 4 lb. in the next month. Family Dr. didn't believe I'm eating, so refused to consider nutritional supplementation and wouldn't do a prealbumin level. I feel I've been left out in the cold to just dry up and blow away. Can eat only small amts., nausea, wt. loss, CONSTANT PAIN. Since tests all neg., it's "all in my head" and wt. loss is my fault because I'm "not eating". What can I do now?
