Topic Overview
What is an ingrown toenail?
An ingrown toenail is a toenail that has grown
		  into the skin instead of over it. This usually happens to the big toe, but it
		  can also happen to other toes. An ingrown toenail can get infected. It may be
		  painful, red, and swollen, and it may drain pus. See a picture of an
		  ingrown toenail.
Anyone can get an ingrown toenail, but adults get
		  them more than children do. People who have curved or thick nails are more
		  likely to get an ingrown toenail. This is more common in older adults.
What causes an ingrown toenail?
An ingrown
		  toenail can have a number of different causes. Cutting your toenail too short
		  or rounding the edge of the nail can cause it to grow into the skin. Wearing
		  shoes or socks that don't fit well can also cause an ingrown toenail. If your
		  shoes are too tight, they might press the nail into the toe and cause it to
		  grow into the skin.
You can get an ingrown toenail if you hurt
		  your toe, such as stubbing it. This can cause the nail to grow inward.
		  Repeating an activity that injuries the nail, such as kicking a soccer ball,
		  can also cause an ingrown nail.
What are the symptoms?
 The main symptom of an ingrown toenail is the
		  pain from the nail growing into the skin instead of over it. If the ingrown
		  toenail gets infected, it might be swollen or red, and it might drain pus. The
		  area around the ingrown toenail is often painful.
How is an ingrown toenail diagnosed?
Your doctor will do a physical
		  exam to diagnose an ingrown toenail. He or she will look at your toe where the
		  nail has grown into the skin.
How is it treated?
You can try the following steps at home to relieve
		  the pain caused by your ingrown toenail and help the nail to grow out
		  naturally:
- Soak your sore toe in warm water for 15 minutes 2 to 3 times
			 each day. 
- Wedge a
			 small piece of wet cotton, such as part of a cotton ball, under the corner of your
			 ingrown nail. This will help lift the nail off of the skin.
- Soak
			 your toe and change the piece of cotton each day until the nail grows out and
			 can be trimmed.
- Do not use a sharp object like manicure scissors to
			 dig under your nail, because the toe might get infected.
- Do not try
			 to use a needle to drain the pus from your toe. This could make the infection
			 worse.
- While your ingrown toenail is healing, wear comfortable
			 shoes or sandals that do not press on your toe.
Use these home treatment steps for 3 days. If they do not
		  help, you might need to see your doctor. Be sure to see a doctor if
		  your toe gets infected. Your toe might be infected if it hurts more than it did
		  before you tried the home treatment. Call your doctor if your toe is red, warm,
		  swollen, or drains pus, or if there are red streaks leading from your
		  toe.
Your doctor might give you antibiotics. If your toenail is
		  very ingrown, your doctor might suggest minor surgery to remove all or part of
		  the ingrown nail. He or she may refer you to a podiatrist. 
During
		  this surgery, the doctor will numb your toe. Then he or she will cut the edge
		  of the ingrown toenail and pull out the piece of nail. To prevent the nail from
		  growing into the skin again, your doctor might destroy all or part of the nail
		  root. This is called ablation. If your doctor removes all or part of your nail
		  but does not destroy the root, it will begin to grow back within a few months.
		  
After the surgery it is important to take care of your toe so
		  that it can heal. Your doctor will give you specific instructions to follow. He
		  or she may tell you to:
- Soak your toe in warm water for 15 minutes 2 to 3 times each
			 day.
- Apply a thin layer of petroleum jelly, such as Vaseline, 2 times each day on the toe where the
			 nail was removed.
- Wear a bandage on your toe.
- Wear
			 loose-fitting shoes that don't press on the toe where the nail was
			 removed.
- Take pain medicine if your toe hurts.
			 Nonsteroidal anti-inflammatory drugs (NSAIDs),
			 including aspirin (such as Bayer), ibuprofen (such as Advil), or naproxen (such as Aleve), might help your toe feel better. Be safe with medicines. Read and follow all instructions on the label.
How can ingrown toenails be prevented?
You may be able to prevent ingrown toenails by wearing roomy and
		  comfortable shoes and socks that do not press on your toes. If you work in a
		  place where your toe might get hurt, wear sturdy shoes such as steel-toed boots
		  to protect your toes.
Be sure to trim your toenails
		  properly. You can do this by cutting your toenail straight across, not curved.
		  Make sure you do not cut your toenail too short. You can also leave your
		  toenail a little longer at the corners to help it grow over the skin.
If you have
		  diabetes or
		  peripheral arterial disease, talk with your doctor
		  before you trim your own toenails. People with diabetes have a hard time
		  feeling their toes and might cut themselves without realizing it. Peripheral
		  arterial disease can cause toes to be very painful. 
Many
		  hospitals and health care centers have foot care clinics, where someone can
		  help you trim your toenails. Ask your doctor to recommend a foot care clinic
		  near your home.
