In June '07, just prior to my Crohn's diagnosis, I had a severe throat infection with 103 fever. I tested negative for strep and mono, but my PCP put me on three different rounds of antibiotics, which caused severe diarrhea, but didn't seem to immediately help the throat infection. It took over a month to clear up an it was very painful! Soon after that I was anemic, high WBC, blood in stool and the eventual Crohn's diagnosis. I really believe it was Crohn's in my throat, although that was never confirmed by a doctor. I suggest that you see an ENT (ear, nose and throat specialist) and make sure they know that you have Crohn's. I gargled with warm salt water, which helps a little, but I was pretty miserable. Sorry you have to go through this!
