So whats some symptoms of perianal Crohn's other than the obvious like my lower back hurts, when I'm inflamed my butt cheeks hurt, and I have frequent urination sometimes also the biggie it's a pain in the ass!! And not to give tmi but have any of the males on here ever get a rash on ur penis? Like dry irritated skin on the head of the penis? I've been married for years so I don't suspect std's I thought it could be a Crohn's thing I heard it can affect the urinary tract as well? I'm only on entocort I wouldn't think this would be a reaction to that
