I am a 60 yr old female, type II diabetic and have had a history of ulcers. I am now experiencing nausea, pain in the abdomen (left side primarily) and may be running a low grade fever. The standard OTC meds for an ulcer provide minor relief but I am having difficulty sleeping. Is it time to go back to the gastroentronologist? What can I do to allevite symptoms until I get in?
