Ringworm is possible.
Also just as a general FYI, OTC hydrocortisone cream is a waste in most situations.
You are on week 11 of a cycle however and no matter how much saw palmetto or the worthless NAC you are taking your liver is going to be stressed. When your liver is stressed these toxins back up in the blood and your body tries to eliminate some of them through your skin. Such excretions can cause irritation of the skin causing flare ups of things like acne, eczema, psoriasis, etc. You will soon be able to tell if its ring worm or not but if it isn't this is my bet.
