text: i was told by a 'foot person' to use sand paper to sand off the shiney top layer of my nail.  Because that is what protects the actual nail bed.  Then i soak a cotton bud/Q-tip with tea tree oil and dab it all over the nail and also as much as i can under the tip.  been doing it for a while now and the discolouring has gotten a lot smaller over the 6 weeks or so.\nNever heard the Vicks vapo rub one though.
