Heyyo,
You can walk onnit, it's suggested no so it can heal faster is all, that and lowered chance of pain.
always have some bandages or something onnit, don't let cotton or wool from your socks get in there, can make it infected.
They took out a chunk of mine, from a hangnail I ripped that got infected. So guys, don't cut your nails too short, and don't ever rip, cut.. rip = bad idea.
my doctor said to soak your toe in warm water with a bit of soap every day, it seems to help the healing process. Helps clear out the puss n' allows the nail to have an easier time growing back.
