Sinus infection can be one of the causes of ulcerative colitis
very interesting study. See link below
Thanks for posting this. It is absolutely the case with me. I have had rhinitis and nasal drip for a long time. In fact my January 2-hour MRI/MRV noted this while everything else was normal.
I had one horrible bout of rhinitis that prevented me from working and I badgered the doctor until I had gone thru 3 rounds of antibiotics and then had full blown UC.
