Then about 2 days ago, I noticed a
white ring forming with a red patch at the tip of my
tongue. It wasnt painful, not sore or anything, just sits there. The ring got bigger today, so I was anxious and went to see 3 GP. 2 of them were saying oral thrush but the other wasnt sure and ordered me STI check. So, before I do the check, just to calm me down, any of you guys experience similar things? Could it be STD?
