I don't have any medical license to be doling out advice on this one but I will say that hydrocortisone cream works for me to at least relieve the itching for 12 hours or so. Cold compresses and NSAIDS can help as well.
Of course, the best treatment when my skin starts to flare is steroids but I try to avoid taking them unless the flare gets bad.
Hope this helps!
