A podiatrist could help you with this isue.
Good luck.
Hmm, me and my dad both have this, and other than surgery there isn't a lot you can do about it other than wearing open toe shoes or shoes that fit properly (or trying to avoid them as much as possible). I don't want surgery so I've just had to deal with the pain :/
You need to get dr and get some antibiotics for the infection, and they will give you further instructions on how to prevent and contain this issue. The more you dig and pick at it the worse it gets, and you'll continue to reinfect the site. My stepson had this recently, same thing, and got antibiotics, cleared up. But you can't cut your nails too close to nail bed on the sides, nails will grow into flesh as they grow out. And they will split and grow out in two pieces as well, so you need to leave them alone first and foremost, and refrain from digging and picking. If something else is necessary then the dr will recommend a treatment. Soak your feet in salty hot water to help clean the infection and salt is a cleanser. But talk to your dr.
