I don’t believe your rash has anything to do with Parkinson’s. But If you have had a rash that long, first talk to your pharmacist. Usually they can give you something.
But if not, I suggest you see your family physician. If he/she can’t help you, get a referral to a dermatologist.

Azilect is the only Parkinson's drug that I have taken that caused rash and that wasn’t till year 3 but everybody’s different it’s a stressful diagnosis and that in itself can cause rash.

Rosie,If you’ve had it for 2 months, I’d see a Dermatologist.(skin Dr). Did you start any new meds during that 2 mo time? Change any facial soaps, creams etc. Think back & see if you changed anything.
