Just Curious, Not Sure.

Patient: Hello, my question is not necessarily to do with ADD/ADHD, i am current taking ritalin for add but i have noticed blotchy red palms just recently, i’m not even certain its due to the medication, my palms are covered with blotchy red spots, the spots are not raised it appears as tho the blotches are beneath the surface, i have no itching.. i was wondering if it could be caused by vasoconstriction and not some underlying problem, perhaps an allergy to medication or bad health indication? thanks.
