So I have had manky dead yellow toenails for ages, I tried to use lockdown to clear them up, using softening stuff, scraping out, allowing to re-grow. It didn't work. Now I'm putting tight climbing shoes on again, and its too painful to climb. I have a swollen side of the nail where I don't have much nail above the skin, and I think it is ingrown out to the side, under the side-skin.
My instinct says I should go in with scissors and cut out as much as possible from under the side-skin to stop it swelling, but NHS/ long term view says that cutting is bad as it can't grow out. Should I just leave it and see a doctor? How has the DIY approach worked for anyone?
