To plonisalmonis,
Don’t be so pessimistic. I know we have the internet in our times, but that doesn’t replace real medical care. If you don’t want to just take meds without knowing 100%, then go to one of your many doctors and have them do fungal tests and cultures on your hand. You might be pleasantly surprised that I’m right. Please don’t base medical decisions on just something you found on some web site. You now understand why I was asking all those questions -in order to help me come to this diagnosis.
