31/female.In 4/07 I had abdominal pain with diarreha then I began experiencing joint pain and swelling.the pain would shift,from a swollen ankle, 2 a sore shoulder,then a finger.I had a lot of gas with muccus.the odor was awful.No solid bowel movements mostly just passing muccus.in May 07,went to Dr,took a stool sample and blood work.stool came back normal,blood showed elevated rhuematoid levels.Dr. said levels were not high enough diagnostically 2 b concerned.symptoms continued.went to another dr.who took more blood.blood work came back normal,scheduled me for a colonoscopy.colonoscopy was done in 08/07,but my symptoms had all resolved,The colonosc came back normal.Dr believed it could have been colitis with reacitive arthritis.3 weeks ago symptoms restarted.When they began I was passing gas and muccus alot.could not pass gas w/o muccus.no joint pain like before,just rare slight twinges,not extreme,no swelling.did have a lot of cramping,naseua and fatigue,lasting 1 day.back was also sore one night.Do have some blood being passed when I wipe or mixed with the muccus,not heavy. I do have a hemmaroid from pregnancy.never have had regular bm's and continue not too. During an episode bm's r loose,solid with loose,solid,other times don't go at all just pass gas with the muccus.symptoms are lessening.not exactly sure what 2 do.I never got a firm diagnosis.do I go back to the Dr and request another scope?if it was ulcerative colitis would that have shown up on my colonoscopy w/o symptoms present?from what I have read about UC it says people pass a lot of blood,wouldn't that have been picked up in the stool sample I gave in May?I also looked up IBS,but could not find joint pain.what should I be asking my dr. and what I should be expecting the Dr to do? what would you expect?I have begun taking a probiotic called Flora Q and Glucosamine .Any help you can give me in regards to what you think I may have and how I should handle this is very appreciated.
