Hi, I'm new to this forum. I have been recently diagnosed with ulcerative colitis and am in the process of testing for Crohn's disease. I have been in a flare up since December 07 and progressively getting worse.
This past week I got a really sore throat, ran a low-grade fever and then two days later started developing ulcers in my mouth and throat. At first, I thought I had strep throat. I went to the doctor who didn't think it was strep and sent me home with an antibiotic just in case. My husband reminded me that Crohn's can affect you from the mouth to the anus and the light bulb went on. I have been reading this forum for a couple of weeks now and remembered reading some of you had experienced mouth sores. I called my GI right away and he took a look and said yes, it could very well be another manifestation of the disease. Well, I have been very stubborn about not taking the prednisone he prescribed for me two months ago. I finally broke down this weekend and started it. Two days later all my mouth sores and sore throat are gone. I'm still waiting for all my other sympotoms to clear up and being able to eat something besides starches and bland food. And, I'm still upset about having to take the prednisone!
So, my long round about answer is yes, Crohn's can be in your throat.
