So I have figured out eating even tiny amount of fish (cooked fish too) and sushi (which I had been eating a lot more of) causes horrible, painful, tender cysts all over my face that benzoyl peroxide, sulfur ointment (Mario Badescu) and topicals will not treat. They just keep getting bigger until I go get a cortisone injection.

They hurt so much. I didn't get it until recently out because it's not publicized but I realized when I went without eating sushi for a while it stopped. I ate a little shrimp one day this week and an ounceof tuna belly five days later. Immediate cysts in a few hours.

For background, I'm 29, I have been on accutane before, and I have been on doxycycline before. I have not taken ANY MEDICATION in a year. I have Naftin samples, Clindamyacin....I just want to make the cysts shrink a little and stop hurting so much. Ideally, I would like to get to a place where I get eat fish and not have this happen too, if that's possible.

I'll admit it, I picked one cyst and it went from pea sized to walnut sized and infected.

If anyone has some advice I'd be grateful. This isn't normal. I can't go the rest of my life without eating sea food, and this wasn't a problem until this year. I don't even know what sort of specialist to ask for help or if an allergist could, because my derm shrugs at me.

I'm not on any medication now but topicals and my skin is crappy (scarring, blackheads, some TREATABLE cysts and papules) without the fish, but this is it. The fish brings out stuff I can't even minimize or start treating until I get to my derm.

Someone on this board suggested Niacin to help. Is that real? Is there an anti-allergen med I can take?
