Is this what a "normal mouth ulcer" looks like for crohn's? I've had blisters with my lupus but never anything like this "hole" in my mouth before. I've tried the salt water and some type of Kanaka stuff but that stuff hurts like nobody's business when I put it on and doesn't seem to help. I will definitely try some of the anti-septic spray. It hurts to talk, eat, laugh...even my teeth hurt at this point.
