I have some kind of nail issue in my nails probably it is nail fungus I am not sure right now I showed it to a doc. He didn't tell me exactly everything but he gave me few medicines for taking orally and something named "nailon" to apply directly but I don't think it made any much difference my nail is decaying from the right side of my thumb and it smells gross and I think some more problem is spreading onto them and also to the other finger please do help.
