Hi everyone, I am hoping someone here can help. About 22 months ago when i got pregnant with my (now 1yr old) son a spot appeared on my left shin. It turned into this horrible rash oval shaped the size of a large softball. It has an outer reddish ring that is super scaly and flaky and the inside of it is my regular skin tone so the rash looks like a large ring. It has been the same size & shape since 22 months ago. it has not faded at all! now about 6 months ago 2 patches popped up on each wrist they are square shaped little patches just like what is the "outer ring" on the shin rash (dry /red/flaky) , then about 4 months ago a little patch popped up on the right shin in the same spot as the left shin.!!! My OB tried me on nystatin...no relief, I tried tea tree oil for months...no relief,,, tried putting oil of oregano drops on it...seemed like it might have gotten a bit better(only tried twice)I've given up soda completely (was a BAD habit) and changed my eating style, begun more exercise. No relief! I live in FL and it is so hot wearing pants now and I am so self concious about people seeing my legs because they make coments like "eww is that ring worm?
Can anyone tell me if this is Psoriasis or eczema? I dont have health benefits for 60 more days so I am hoping I can find something here. I have pics if anyone could possibly tell me and what to do for it.
Blessings!

Also I am a breastfeeding mom still
