Hi
Ouch that sounds really painful! I was having that problem recently in my bad foot, and the doctor did a procedure where he removed the whole right side of my nail that borders the skin. It is now growing in perfectly straight and will prevent further ingrowns! It was not a big procedure - got it done the day-of at the podiatrist's office at a regular visit. If you aren't into that idea, you should at least get it looked at by a podiatrist. They can give antibiotics as well as cut back the nail. Good luck!
