Due to onchomycosis, I have some moderate discoloration on about 50% of one toenail and just a little bit on the other big toe. I am wondering how quickly this usually goes away after starting Terbinafine. Is the medium-brown color (it looks a little bit like dried blood) likely to take several months or more to go away, or does it go away within a few weeks? I know it can take months or years to treat, but I'm embarrassed about the problem and don't want to have to hide my toes if I don't have to. Thanks...
