Ingrown toenails can be painful and inconvenient, and worst of all, they can get infected easily. If you are suffering from an ingrown toenail that has become infected, you'll need to treat the infection to prevent the condition from worsening.^{[1]

Research source} To remove infection from an ingrown toenail, soften the nail in warm water before carefully propping up the edge and applying antibacterial ointment directly to the infection beneath the nail. While this is a decent start, it is strongly advised to visit a podiatrist for proper treatment instead of relying on home treatment for the infection.

Treating the Nail

1
Soak your toe. In order to reduce the pain and swelling involved with an ingrown toenail, soak the foot with the ingrown toenail for 10-20 minutes in warm, soapy water, three times a day for one to two weeks. The Epsom salt can also help with pain and inflammation.^{[2]

Prop up the edge of the nail. To relieve the pressure under the ingrown edge of the toenail, doctors sometimes suggest propping the nail up slightly. This is done by sticking a small piece of cotton or thick floss under the edge of the nail. This technique helps pull the nail away from the skin, so it no longer digs into the skin.
- If you use cotton, you can dip it in antiseptic to help ease the pain and prevent infection under the nail.
- If the nail is infected, this may also help to soak up any moisture that is trapped under the nail.
- If you use thick floss, make sure that it is unflavored and unwaxed.
- Do not insert a metal tool under the nail to try to insert cotton or floss. This could damage the toe further.^{[6]

Apply antibacterial ointment. Antibacterial ointment is helpful when dealing with an infected ingrown toenail. Before you apply the ointment, dry your toe completely. Cover the infected area with an antibacterial cream. Apply the ointments in a thick coat over the infected area of the toe. Wrap your toe with a bandage such as a large band-aid. This prevents debris from entering the wound and keeps the ointment in place.
- Use antibacterial ointments such as Neosporin.^{[7]

Visit a foot doctor (podiatrist). Ingrown toenails that become infected should not be treated at home, which is true for most infected wounds. Visit a podiatrist, more commonly known as a foot doctor, to get treatment for your infection. If the infection and nail are bad enough, minor surgery may be required. For the most part, however, a simple surgical procedure involving numbing the nail bed and then removing part of the ingrown nail with clippers or scissors by the doctor,
- You may be prescribed oral antibiotics, which are taken by mouth, to help fend off further infections.^{[8]

Avoiding Common Misconceptions

1
Do not cut the nail. A common misconception about having an infected ingrown toenail is that it needs to be cut. Contrary to popular belief, cutting the nail can make the infection worse. It can also cause more ingrown toenails in the future. Leave the nail uncut, and prop it up to relieve pressure.
- The toenail may need to be cut by a doctor, but should not be done at home in ‘bathroom surgery’.^{[9]

2
Do not dig under the nail. It may be tempting to try to relieve pressure or lift the nail from the skin by digging at the skin underneath. Do not do this because it can intensify an infection and make the ingrown nail worse.
- Stay away from your toenails with tweezers, orange sticks, clippers, files, or any other metal tools.^{[10]

3
Do not attempt to drain an infection. There is a popular conception that you should use a needle to puncture a blister or a pustule caused by an infection. You should not do this because it will just make it worse. Even if you use clean tools and a sanitized needle, you can cause some serious damage by poking and prodding at a blister or infected wound.
- Avoid touching it with anything other than a cotton swab or bandaging materials.^{[11]

Do not cut a ‘V’ in the nail. According to some old folk healing methods, you should cut a ‘V’ shape in the top of the infected toenail to relieve the pressure, which in turn will heal the nail. However, doing this does absolutely nothing except create a jagged edge on your nail.
5
Avoid coating your toe. Do not believe urban health myths such as rubbing coal on your toe to make an infection go away. Although some people swear by this method, the coal won’t benefit the infection or the ingrown nail at all. In fact, this method may make it worse. In general, you should not put anything on your toe or the infected area except for antibiotic cream or bandages.

Expert Answer

Hydrogen peroxide is a good agent to control infection and help relieve some of the pus and pain involved with an ingrown toenail. I would put a band aid over the nail after I cleaned it out with peroxide.
