The worst problem I've ever had with my feet have been the odd mild in-grown toenail, which was never painful enough to require surgical intervention. In the past several months I've suddenly had 1) a really bad, deep callous, which made it very painful to walk normally, and 2) yesterday I was startled when I noticed that the toenail on my left big toe is suddenly starting to lift off! WTF?! This is freaking me out a little - what happens if it falls off??
A few weeks ago I did notice that the older half of the nail was a bit yellowed, so I applied a drop of grape seed oil a few times (also in hopes of softening the nail to ease the in-grown problem that has resurfaced as well). Now that it's lifting off I'm applying a drop of tea tree oil in hopes of killing this fungus.
The best part is that my doctor's office never bothered to phone me back when I left a message, asking them to arrange a podiatrist appointment. A-holes.
