You may have seen instruction that say to cut your toenails straight across. However, this often leaves a sharp corner on the nail. It makes more sense to trim your nail s with contour of the toe, being sure all sharp edges are cut or filed smooth. The length o the toenail should be even with end of the toe.
It is not good idea to cut into the edges of the toenail or to try to treat ingrown toenails yourself. This sort of “bathroom surgery” is very risky for people with diabetes. The main point of safe toenail trimming is that if you do injure yourself; seek medical attention for any injury that does not heal promptly. If you have nerve damage or poor circulation and you cut yourself, see your provider right away. Do not wait until you develop an infection.
