Hello dear I understand your concern It could be inflammatory disease, gastroenteritis, inflammatory bowel disease, polyp, aspirin use. I advise you to consult the gastroenterologist as early as possible and undergo following investigations abdominal USG, colonoscopy , stolol test, CBC and CRP. Treatment will depend on the cause. Meanwhile take tablet diclyclomine and O2. Drink sporolac powder Drink plenty of lukewarm water. Take soft diet like rice, bread, banana, applesauce. Take proper rest. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
