Common causes of ingrown toenails include wearing shoes that are too small, improper cutting of toenails, toenail injuries and having toenails with a deep curve, states Mayo Clinic. Ingrown toenails can cause pain, redness, swelling and infections around the toe.
If an ingrown toenail is causing severe pain, has pus or a spreading redness, Mayo Clinic recommends seeing a doctor. Diabetes or other conditions that cause poor circulation can result in complications with ingrown toenails, and doctor consultation is also recommended in this situation. If left untreated, an ingrown toenail has the potential to infect the bone underneath.
An ingrown toenail grows into the skin and not over it, explains Everyday Health. There are a number of at-home remedies one can use to treat an ingrown toenail.
One of these treatments is to soak the afflicted toe in warm water for 15 minutes, two or three times a day. During the day, a small piece of cotton is wedged under the nail to help lift it up. The toe is soaked, and the cotton is changed every day until the nail is long enough to be trimmed. Comfortable shoes that don't press on the toe while it's healing can help relieve the associated pain, advises Everyday Health.
