...doctor can't even figure it out.? For over 2 months now i have had this ring shaped wound on my knuckle and it wasn't going away. i thought it was ringworm so i used lamisil and lotrimin but nothing was working. So then i looked up home remedies for ringworm and found salt and vinegar would work. so i peroxided it a bunch and then put sea salt on it for a half hour. then tried vinegar a few times. i did this for a few days and all of a sudden my hand got WORSE! all these little clear blisters showed up on my fingers and rest of the back of my hand. it looks a lot like athletes foot, and acts like athletes foot. If the blisters pop, it spreads even more. i went to the doctor and got 4 prescriptions for it because he doesn't even know what it is. obviously it wasn't ringworm because it didn't spread like ringworm and honestly didn't look a lot like ringworm...it was just in an oval/ring shape so that's what we concluded in the beginning. help!
