I've never taken accutane and my EC is pretty much lifelong since I was a young child.
You can see how many other symptoms I have from past posts. My rectal itching has improved/stopped now which really was a secondary way my body was telling me something is not right. I've a load of other skin problems which have reduced. I am still getting flares occasionally but they are mild. For example I had a soy sauce yesterday which was gluten free and I'm thinking that may be caused mild inflammation because I get the anal itching/irritation and the lips are more drier. As I say the gluten free makes the biggest difference, it made my lips suck in huge amounts of moisture, no matter how much I licked or didn't lick, how much product I applied, it would cause them to get chronically dry, crack and bleed.
I hope the gluten issue is the reason some of us have EC.
