Some months back, my brother's doctor revised his diagnosis from histoplasmosis to sarcoidosis. Not before he'd spent $1200 on antifungal medication.

My brother landed in the hospital again this weekend suffering from dehydration and anemia, after several days of fevers and sweats.

Another round now of CT scans and bone marrow tests, with the addition of a GI scope for ulcers -- caused, if they exist, by the prednisone used to treat the sarcoidosis.

Poor guy. He has never been ill before. Prior to all this he'd spent an overnight in the hospital with a broken arm when he was 12 years old. And he is a lousy patient. Big baby.
