you can go to the county health department. did you have to get a TB test before you entered CNA school? if you did, we can rule that out. if not, go get one. and do what Soidhonia suggested also. they are free.

incidentally, a pediatrician is a real doctor who went to regular med school and then picked a speciality.....children. he can be trusted to diagnose you even though you're over 18........xoxoxo pat
