So, for as long as I can remember, literally at least 20 years, I've had one toe (the little one on my right foot) that has a really thick toenail. It's kinda flakey and if I trim or file it too much, the nail seems to bleed. It's not discolored and doesn't appear to be ingrown or a fungus (especially as it's never spread). Has anyone heard of something like this or how to treat it?
