I am 54, 170 lbs, back surgeries that I am on pain meds for every day. One of the meds is Ibuprofen. I ve stopped the Ibuprofen for the last 2 days. For the last three days I ve been having severe epigastric pain, midline, with gas, smelly, soft yellow stools, bloating, don t want to eat. More pain after I eat. It hurts to put pressure on my stomach area. I am under a lot of stress this week. Can all this be caused by stress or should I be going to the doctor? Thanks, Gwen
