I've had stomach pains for one year now and they don't seem to be getting any better. I've had a colonoscopy, endoscopy, multiple x-rays and ct scans, blood tests, stool tests, allergy tests, breath tests, stomach emptying test, ultrasound, and one where i can't remember the name of it but i drank white chalky liquid and they watched my stomach and how the liquid passed through it to look for abdominal artery constriction and nothing was found on any of these tests. I've tried an ibs diet, liquid diets, giving up dairy and wheat, flagyll, amitiza, prednisone, cyproheptadine, zoloft, bentyl, and right now I'm on lexapro for what doctors presume is a seratonin imbalance in my stomach (because my twin has OCD they thought this might be related seeing as how she had a seratonin imbalance in her brain). My symptoms are abdominal pain that is usually under the left rib but sometimes under the right or just complete upper in general and sometimes it spreads to my lower stomach and back, weight loss, nausea, dizziness, constipation, pale stool, bloating, loss of appetite, and intolerance to cold. I am so desperate for an answer because i feel like the lexapro will not work. I have been taking it for almost a month now and at first i believed i was getting better but now Im back feeling miserable. The pain is so debilitating and makes me have to miss so much school and other things. i really need help.
