I can't believe there is not a dermatologist than can see you now... that is awful. I would try a walk in clink or a Primary Doctor maybe if they give you a referral you can get in when the rash is there.
I have a rash on my face and now after reading your post it does get worse before my cycle, at least it is now. It is terrible and annoying.
I wish you well....sorry you are feeling so bad
