Re: Dry skin patches
SanDiego - this is quite puzzling isn't it? I'm sure if your doctor(s) both think there is nothing wrong, it is time to ask for a referral to a dermatologist. I hope you can get in soon. I've forgotten where you are from (San Diego?), but in the meantime for the itchiness, you could try an allergy tablet or allergy cream, for the itchy skin. A pharmacist could help you pick one out.
I hope this helps you in the meantime, and that you get time quickly with a dermatologist to figure it out.
Wishing you peace and comfort,
