I've been freaking out for months over my tongue. Right in the back, I have a section of white-ish taste buds. I'd say since April I've been convinced I have oral thrush. When I brush my teeth in the morning, it mostly goes away, and then by night I have more and I brush that away, but it's back again by morning. It doesn't hurt or bleed and I don't have a sore throat, but what if its just a mild case of oral thrush?? My friends say their tongues look the same, but what do they know?? I went to my school doctor in May about it and she said it looked fine, but I'm worried that since oral issues are not her speciality, she may have not been able to identify it. What if this is a sign I have HIV? I'm going crazy, please help!!!
