I think I have ringworm on my chin. There are several small bumps in one area, about the size of a time. It doesn t itch much. At first I thought it was a few pimples, but I don t break out much and the fact that it was all clustered together and the white heads just little dots, had me questioning. I went to a new dermatologist and he said it was most likely acne and tried to sell me a $80 retinal cream (even though I told him I normally don t have acne). He then said that a cortisone shot would clear it up quickly. That was 5 days ago and if anything it has gotten worse. I ve scoured the web and the only thing it looks like is ringworm. I have been using tea tree oil and that seems to dry it out. I m HOPING that it will go away quickly as it is on my face and not too attractive. 1. Could the cortizone shot have made it worse? 2. Should I see a general practice doctor to get a diagnosis or wait a few more days and see how it does? 3. I also heard about using apple cider vinegar as that would get rid of it quickly, but I have sensitive skin. Could that cause scarring or damage? Is it harsh? Thanks so much for taking the time to answer my questions!!
