What is an ingrown toenail? —
This is when the side or corner of the toenail grows into the flesh around it. It usually affects the big toe.
What are the symptoms of an ingrown toenail? —
The symptoms include pain, redness, and swelling where the nail has grown into the flesh.
Is there a test for an ingrown toenail? —
No. Your doctor or nurse should be able to tell if you have it by learning about your symptoms and doing an exam.
What can I do on my own? —
You might feel better if you:
●Place a small piece of a cotton ball or some dental floss underneath the nail to take pressure off the toe (figure 1).
●Soak the foot in warm, soapy water. Do this for 10 to 20 minutes, 2 to 3 times a day for 1 to 2 weeks. You can also use 1 to 2 teaspoons of Epsom salts (available in pharmacies) in the water instead of soap.
Should I see a doctor or nurse? —
See your doctor or nurse if the redness and swelling get worse and there is pus.
How is an ingrown toenail treated? —
If the treatments you tried on your own don't help, your doctor might cut away part of your toenail. They will first inject a medicine to numb your toe. Afterward, you need to:
●Clean the area 2 to 3 times a day. Make a mixture of equal parts water and hydrogen peroxide, and dab it on your toe with a cotton swab.
●Put antibiotic ointment on your toe. Examples include bacitracin or mupirocin (brand name: Bactroban).
Can an ingrown toenail be prevented? —
You can reduce your chances of getting an ingrown toenail if you:
●Wear shoes that are not too tight around your toes (figure 2).
●Cut your toenails straight across and not too short (figure 3).
