You're right, Madelyn, it's good and bad news all at once.
I've had an assortment of skin problems since my mid 20's, which started with sudden summer heat rashes. A few years later I developed itchy dermititis around my nostrils ("just stress", I was told), then stubborn tiny scabs in several spots (one on my left calf, two on my scalp, another on my right arm) which my GP called "harmless Keratitis" and not to worry about it...

I believe it's all PD-related. Or should I say, it's the same underlying cause that also triggered my PD? Too bad that western medicine is based on "specialties" and no specialist ever has the training to see all symptons as a whole picture of any one disease.
