Hi, Thanks for writing in. To be able to help you better, I would need answers to the following questions: a. Which cancer was your husband suffering from? b. Which pain pills has he been taking? c. Was an upper GI endoscopy done for him? d. Has he undergone any surgery? It is possible that your husband is having the pain in his stomach due to radiation enteritis. This would particularly be true if his upper GI endoscopy has been normal and he is not receiving non steroidal anti inflammatory drugs right now. The following would help: a. Avoiding alcohol and tobacco, milk products, coffee, tea, chocolate, and soda drinks with caffeine, foods containing whole bran, fresh and dried fruits, fried foods, nuts and seeds, popcorn, potato chips, and pretzels, raw vegetables and rich pastries and baked goods If the upper GI endoscopy and colonoscopy are normal, please speak with your physician about a small bowel capsule endoscopy. However, chronic radiation enteritis has no proper treatment. The only way out may be to resect the affected segment in surgery. Awaiting your reply
