Hi, I had an ulcer back in 199o's.  It improved, but whenever I take ibrofen etc. for a few days then I get this knawing pain on my left side under my rib cage.  I have been taking Musinex for the past 4 days. 4 tablets a day.  I am wondering if that is why the past couple of days & yesterday afternoon being the worst for a couple of hours the sharp pain in my lower pelvix area was really bad. I discontinued taking the Musinex yesterday. During the nite I only had a twinge of pain. Now my upper stomach just feels a little uncomfortable. I am 68, female, actively working. 5'10" & 215 #'s.
hi, your pain may be a gastric ulcer. it is a risky condition and i suggest getting a medical or surgical opinion.
