I have an ingrown toenail, is it possible that it heals by itself?

Ingrown toenail: Most ingrown toenails will not heal by them self without treatment. Soaking the toe in epsom salts an warm water may help to alleviate the discomfort but you should see your podiatrist for further evaluation if the area is red and swollen.

Pain, redness.: Redness and pain along the nail border, sometimes with drainage indicates an "ingrown toenail". If your ingrown nail is infected, you'll likely need antibiotics, and possibly a nail procedure. While waiting to see your doctor, soak the toe 10 min/day in luke warm water and epsom salts, use a small amount of topical antibiotic ointment, and cover with a bandaid.

It may hurt, but...: It's possible but unlikely that it will just heal. There is a small piece of nail still embedded in the corner. You need to get that out. If you can't get it out on your own, a podiatrist can. Sometimes this can be done without numbing the toe, but often, anesthesia is necessary. If it is a chronic condition, there is a very successful surgery that can be done to permanently correct the problem.
