Hi all, haven't posted here for awhile. I was diagnosed with IBS after a colonoscopy about 3.5 years ago. My symptoms were constipation for many days, followed by severe pain and diarrhea, then the process would repeat. After each of the diarrhea episodes I would have a low grade fever and chills. I would get these episodes about 5 times a month and it was awful. Two years after my diagnosis of IBS, I was diagnosed with Generalized Anxiety Disorder and began taking Paxil. The frequency and severity of my attacks greatly reduced until I got them maybe once a month. Now I may only get an "attack" every 2 or 3 months. In April I switched to Lexapro, but it hasn't seem to affect my IBS, which is good. My question is, I still get the low grade fever/chills after an attack. I know they say that those symptoms are usually a sign of an infection, but the fever goes away after I take one dose of Tylenol and doesn't return. I always thought it was just my body reacting from the trauma it went through with the pain/diarrhea. Any thoughts? I was starting to think maybe I have Crohn's or Ulcerative Colitis but I have none of the other symptoms, other than the IBS ones. Thanks for any input,agr8chick
