It has been off and on for about 2 weeks. I just assumed it was because I was on a new medication. (Mobic) I'm a former Gastric Bypass patient (8 yrs ago). I quit taking the medication 4 days ago. I thought maybe I had an ulcer but my husband says it sounds like what he went thru when he had gallstones. I was thinking about going to the ER. My BP is normal. I've been stressed out lately due to taking my pre-admission nursing exam so I thought maybe it was stress. I also have IBS. (Irritable Bowel Syndrome) I take medication for it but I wonder if that and the stress are what's doing it. I was thinking about going to the ER but I really can't afford it. Any thoughts?
