Narcolepsy Support Group
A sleep disorder (somnipathy) is a disorder in the sleep patterns of a person or animal. Some sleep disorders can interfere with mental and emotional function. If you are having trouble falling asleep or having some other kind of sleep disturbance, this group is for you.
I always thought it was weird that it wasn't just my face (like when I was teen) but my stomach and neck mostly.
However, we've had discussions in the past about how the medications we take tend to cause excessive sweating...I would bet that has a lot to do with increased acne and other skin irritations, especially on the back or chest.
Pam, your wording of the question, by indicating you were diagnosed and THEN noticed the change adds to my suspicion that this may be part of the answer for you.
