Hello all, I was diagnosed with IBS in Febuary after getting a colonoscopy . Recently I have been fighting a throat and ear infection since the middle of February and its finally getting better. However, Last week i had a bad pain on my left rib, like the last bone of my rib cage that woke me up at night. I went to the doctors the following day and the doctor believed it was just my infection spreading to to the cartilage between my ribs. I haven't had the pain as bad as that night since, how ever its dull and achey and rumbles from time to time. I have also been sweating alot the past few days with out fevers and have had night sweats and have been having a few more BMs a day.Today I had loose stools that look dark with gray in it.Dose this sound like a case of IBS and remnants of the antibiotic or this infection I had ?I have read where people have IBS pain under their ribs due to the colon bending there.
