Hi my toe nails are separating from the nail beds from the top of the nail. By top I mean the the edge that you trim. My right toe was bruised and the surface became white where it was detaching. This has been going on for over a year now and now the big toe on my left foot has also started to go white and detach and I'm noticing it in other toenails. I'm doctor carried out tests for fungus but the tests came back clear. I don't wear tight fitting shoes so I don't know what it could be but I don't want to loose my nails.

Hope someone might be able to help
