What do I do if I have an ingrown toenial?

Paronychia. I have not found home remedies to be particularly effective in small infections at the nail/skin interface. Unless you know how to open the cuticle and drain the pus, my advice is to skip the home remedies and see a physician who understands the problem and can drain the abscess.
Soak and cotton. Home remedies for ingrown toenails include soaking in a solution of warm water and epsom salt. Some have also found benefit to putting a small wad of cotton between the nail and the nail fold (skin). Unfortunately, home remedies for ingrown toenails are not very effective. Lack of improvement or pus warrants a visit to your doctor or podiatrist.
