I cut my toenail wrong and now it is ingrowing is there anyway to help this in the home without going to a podiatrist?

Cut a small wedge in the center of the nail. Then it will grow toward the wedge and away from the toe.

I've heard of this " do I cut the wedge where the at the end in the centre ?

If you were normally trimming your nail, you would trim it basically straight. Instead of that, you trim it and cut a small 'V' or 'U' shaped wedge in the middle of the trim line.
Your nail should look like this when you are through ---> ______ ______
\-/

Formatting for my diagram did not work. It will have a v shape in the middle of the trim line of the nail

I will try this and let you know if it worked thank you for your help
