About a year ago my big toenail fell off. I never remember injuring it. Anyway, I went to the podiatrist and had the nail tested for fungus (none found). Now I have what looks like a double nail growing (or maybe it's a ridge).Two of my toenails have a brownish-blackish spot, the nails are all thickening, and I have another nail with a very pronounced ridge. I thought I'd try the dermatologist this time. Does it sound like a fungus? Does anything over the counter kill it?
