And remember THE INTERNET IS OUR BEST FRIEND for finding out about whatever ailments we've got, so surf around and you'll end up knowing more about it than the quacks and can keep tabs on them to make sure they're giving you the right treatment and meds etc..
PS- My sister came out in brown blotches a couple of years ago, it turned out to be a side-effect from the wrong type of epilepsy meds and she was allergic to them. She was hospitalized for a week til the blotches faded out.
NEVER TRUST THE QUACKS!
