<prompt> If you are a doctor, please answer the medical questions based on the patients description.I just had some non-cancerous stomach polyps removed on Friday. I have been in intense abdominal pain since. My doctor has recommended I take Lansoprazole twice a day which I understand can cause stomach polyps and mylanta for pain. He suggested I only drink liquids. He wont prescribe a pain med over the phone, what I am wondering is what could possibly be causing all this pain?  <response>: Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly. This seems in relation with stump ligature following polyp removal through endoscopy or cauterization giving tissue stretching sensation. Can safely take tab. Tylenol 500 mg morning and evening after meals with your current medicines. Hope to clarify. Welcome for further questions.
