What Causes Ingrown Toenails to Keep Coming Back?

If your ingrown toenail keeps coming back no matter what you do, you are not alone, and you are not doing something "wrong." Recurring ingrown toenails are one of the most common foot problems we treat at Northern Ankle Foot Associates. Studies show that ingrown toenails affect about 2.5% to 5% of the general population, and they account for roughly 20% of all foot-related visits to a doctor. The big toe is the one involved in about 80% of cases.

The short answer to why they keep coming back is this: the root cause was never fixed. Maybe it is the way the nail naturally grows. Maybe it is how you trim it. Maybe it is your shoes, your foot shape, or a health condition that changes how your nails grow. Whatever the reason, the nail will keep digging into the skin until that underlying issue is addressed.

In this article, we will go through every major reason ingrown toenails come back, what warning signs to watch for, how a foot and ankle specialist can stop the cycle for good, and what you can do at home to lower your risk.

What Is an Ingrown Toenail?

How It Starts

An ingrown toenail happens when the edge or corner of a toenail grows into the soft skin next to it. This creates pressure, then irritation, then swelling and pain. If the nail breaks through the skin, bacteria can get in and cause an infection. The toe may turn red, swell up, feel warm to the touch, and sometimes leak pus.

It almost always happens on the big toe. The outer edge of the nail is affected about twice as often as the inner edge.

The Three Stages

Doctors divide ingrown toenails into three stages based on how bad they are:

• Stage 1 (mild): The skin next to the nail is red, slightly swollen, and tender when you press on it. There is no infection yet.
• Stage 2 (moderate): The swelling is worse. The skin may start to grow over the edge of the nail. You might see some drainage or pus. Pain is more noticeable.
• Stage 3 (severe): The tissue around the nail is very inflamed. Extra tissue called granulation tissue has formed. There may be a clear infection with significant pain, pus, and swelling.

Most people try to handle stage 1 at home. By the time they see us, they are often at stage 2 or 3, and the nail has already come back multiple times.

The Real Reasons Your Ingrown Toenail Keeps Returning

Improper Nail Trimming

This is the number one cause of ingrown toenails, and it is also the most fixable. Cutting your toenails too short, rounding the corners, or tearing the nail instead of cutting it clean can all set the stage for an ingrown nail.

when you rip or pick at the nail, you can leave behind tiny sharp pieces called nail spicules that dig into the skin. If you cut the corners of the nail and either leave a piece that continues to grow into the nail border, or you cut the skin as you cut your nail, the dirty nail will infect the open skin.

The fix sounds simple: cut straight across and do not go too short. But for people with thick nails, curved nail beds, pressure from the nail,, doing this correctly at home can be harder than it sounds.

Your Natural Nail Shape

Some people are just built with nails that curve more than others. A nail plate that is naturally wide, fan-shaped, or has deep grooves on the sides is more likely to press into the surrounding skin. This is genetic. You inherited it, and no amount of careful trimming will completely change the shape of the nail.

If your parents or siblings also deal with ingrown toenails, there is a good chance your nail shape is a big part of the problem. In these cases, a minor in-office procedure by a foot specialist is often the best way to break the cycle permanently.

Tight or Narrow Shoes

Shoes that squeeze the toes together push the skin into the nail edge. Over time, this constant pressure encourages the nail to grow into the skin rather than straight out. High heels, pointed dress shoes, and athletic shoes that are too small in the toe box are all common offenders.

This is why ingrown toenails are especially common in teenagers (whose feet are still growing and who may wear shoes that are too small) and in adults who wear tight work shoes or heels daily.

Toe Injuries and Trauma

Stubbing your toe hard, dropping something heavy on your foot, or repetitive impact from activities like running or soccer can damage the nail bed. When the nail bed is injured, the nail may grow back thicker, curved, or in an irregular direction. This damaged growth pattern makes ingrown nails more likely with every new cycle of growth.

Athletes who play sports that involve a lot of stopping, starting, and toe pressure are especially prone. We see this often in runners, soccer players, and basketball players.

Sweaty Feet

This one surprises a lot of people. When your feet sweat heavily, the skin around the toenails becomes soft and damp. Soft skin is easier for a nail edge to push into and pierce. This is one of the reasons ingrown toenails peak in teenagers, whose hormonal changes cause more sweating, and in people who wear enclosed shoes in hot weather for long hours.

Keeping feet dry, changing socks during the day if needed, and choosing breathable footwear can all help reduce this risk.

Fungal Nail Infections

A toenail fungus infection can change the shape, thickness, and texture of the nail. Fungal nails often become thick, crumbly, and warped. This distorted nail is much more likely to grow into the surrounding skin. If the fungus is not treated, every new nail that grows in will carry the same problems.

Treating the fungus and the ingrown nail at the same time is important. Fixing one without the other is like mopping the floor while the faucet is still running.

Previous Ingrown Toenail Surgery That Did Not Fully Work

If you have had an ingrown toenail removed before but it came back, the nail root may not have been fully treated during the first procedure. A standard nail removal takes off the piece of nail that is causing trouble, but if the nail matrix (the root where the nail grows from) is left intact, that section of nail will grow right back, and it may grow right back into the skin.

A procedure called a partial matrixectomy removes the offending nail border and then treats the root with a chemical (usually phenol) to stop that section from regrowing. This is the most reliable way to prevent recurrence. Studies show that about 27% of patients who had a previous surgical procedure for ingrown nails experienced the nail coming back. A matrixectomy significantly lowers that number.

Health Conditions That Affect Nail Growth

Certain medical conditions can change how your toenails grow and how your body heals. Diabetes is a big one. Poor circulation and nerve damage from diabetes can make nails thicker, more fragile, and harder to care for. Infections also develop faster and heal slower. People with diabetes who get ingrown toenails need to take the problem seriously and see a specialist early. If left untreated, a simple ingrown nail in a diabetic foot can turn into a serious infection.

Other conditions that can contribute to recurring ingrown toenails include arthritis which can limit your ability to reach your toes for proper nail care, as well as circulatory problems and immune system issues.

Aging and Nail Changes

As we get older, toenails naturally get thicker and harder to cut. They may also grow more slowly but with more curve. Older adults are also more likely to have reduced flexibility, making it harder to trim nails properly. All of these factors add up to a higher risk of ingrown toenails returning after the age of 50.

What Gets Mistaken for an Ingrown Toenail

Not every painful, red, swollen toe is an ingrown toenail. Several other conditions can look and feel very similar. A paronychia is an infection of the skin right next to the nail, often caused by bacteria or a hangnail, and it can happen without the nail actually growing into the skin. A subungual hematoma is blood trapped under the nail from an injury. Bunions can cause pressure and redness on the big toe that gets confused with nail problems. And in rare cases, a growth called a pyogenic granuloma or even a tumor under the nail can mimic the look of a chronic ingrown toenail.

This is why getting a proper diagnosis from a foot specialist matters, especially if the problem keeps coming back despite treatment.

How a Foot and Ankle Specialist Treats Recurring Ingrown Toenails

Conservative Care for Mild Cases

If the ingrown toenail is in the early stage and has not happened many times before, conservative treatment may be enough. This includes soaking the toe in warm water to soften the skin, gently lifting the nail edge and placing a small piece of cotton or dental floss under it to guide it away from the skin, applying antibiotic ointment to prevent infection, and wearing shoes with a roomy toe box.

These steps can work for a first-time mild case. But if the nail has come back two, three, or more times, conservative care alone is unlikely to solve the problem for good.

Partial Nail Removal With Matrixectomy

This is the gold standard for recurring ingrown toenails, and it is a procedure we perform regularly at our practice. Here is how it works: the toe is numbed with a local anesthetic. The section of nail that keeps growing into the skin is carefully removed. Then the nail root (matrix) in that area is treated with a chemical to stop that part of the nail from growing back. The rest of the nail stays in place and looks normal.

The procedure is done right in the office and takes about 5minutes. Most patients feel relief almost right away. Healing takes a few weeks, and the recurrence rate is very low(15%) when the matrixectomy is done correctly.

Dr. Robyn Joseph and our team use this approach because it treats the root cause, literally. It is not about trimming the nail again and hoping for the best. It is about stopping the problem at its source.

Total Nail Removal

In rare cases where the entire nail is severely damaged, thickened, or repeatedly infected, removing the full nail and treating the entire matrix may be the best option. This is less common but sometimes necessary when the nail has been a source of chronic pain and infection for years. The toe heals well, and while the nail may not grow back (which is the goal), the toe looks and functions normally.

How to Prevent Ingrown Toenails From Coming Back

Trim Your Nails the Right Way

Cut straight across with clean, sharp clippers. Do not round the corners. Do not cut too short. The edge of the nail should be roughly even with the tip of the toe. If your nails are thick or hard to cut, soften them first by soaking your feet in warm water for 10 to 15 minutes before trimming.

Wear the Right Shoes

Choose shoes with a wide toe box that gives your toes room to move. Avoid shoes that squeeze, pinch, or press on the toenails. If you wear work boots or athletic shoes, make sure they fit properly and are not too tight in the front.

Keep Your Feet Clean and Dry

Wash your feet daily and dry them well, especially between the toes. Change socks if your feet get sweaty during the day. This keeps the skin around the nails firm and less likely to be pierced by a growing nail edge.

Do Not Pick or Tear Your Nails

Resist the urge to rip off a hangnail or tear a toenail. This can leave behind sharp fragments that grow into the skin. Always use proper nail clippers.

See a Specialist if the Pattern Continues

If you have had two or more ingrown toenails on the same toe, it is time to see a foot and ankle specialist. Home care is great for prevention, but it is not enough to fix a nail that is structurally prone to growing into the skin. A quick in-office procedure can end the cycle for good.

Frequently Asked Questions

What Causes Recurring Ingrown Toenails?

The most common causes are improper nail trimming, a naturally curved nail shape that runs in families, wearing shoes that are too tight, past toe injuries, toenail fungus, and health conditions like diabetes that change how nails grow. If the root cause is never addressed, the nail will keep growing into the skin no matter how many times it is trimmed or removed.

Will I Ever Stop Getting Ingrown Toenails?

Yes, in most cases. If the ingrown nail is caused by a fixable habit like trimming or shoe choice, changing those habits can stop the cycle. If the cause is the shape of the nail itself, a partial matrixectomy performed by a podiatrist who treats ingrown toenails can permanently prevent that section of nail from growing back. Most patients who have this procedure do not deal with the problem again.

What Does a Serious Ingrown Toenail Look Like?

A serious ingrown toenail has heavy swelling, redness that spreads beyond the toe, pus or drainage, and sometimes extra tissue growth around the nail edge. The toe may throb even when you are not touching it. In severe cases, red streaks may appear moving away from the toe, which is a sign the infection is spreading and needs immediate care.

Is It Okay to Dig Out an Ingrown Toenail?

We strongly advise against it. Digging at the nail with sharp tools at home can push the nail deeper into the skin, introduce bacteria, and cause a worse infection. It can also damage the nail bed, which increases the chance of the ingrown nail coming back. If the nail is painful and embedded, let a specialist handle it safely.

How Do Podiatrists Treat Ingrown Toenails?

A foot specialist will first examine the toe to check for infection and determine the stage. For mild cases, conservative care like soaking and gentle lifting may be tried first. For recurring or moderate to severe cases, a partial nail removal for ingrown toenails with matrixectomy is the most common and effective treatment. The procedure is done in the office under local anesthesia and takes about 15 to 20 minutes.

Are Ingrown Toenails Your Fault?

Not always. While habits like cutting nails too short or wearing tight shoes can cause them, many people get ingrown toenails because of their natural nail shape, genetics, a past injury, or a health condition. Blaming yourself does not help. Getting the right care does.

Final Thoughts

Ingrown toenails that keep coming back are more than just annoying. They hurt, they can get infected, and they can make everyday activities like walking and wearing shoes miserable. The good news is that in most cases, the cycle can be broken. Whether it is a simple change in how you trim your nails or a quick in-office procedure to permanently stop the nail from growing into the skin, the right solution depends on what is causing the problem in the first place.

Our team at Northern Ankle Foot Associates specializes in diagnosing and treating ingrown toenails at every stage. We take the time to figure out why the nail keeps coming back, not just deal with the immediate pain. If you are tired of the same toe swelling up every few months, it is time to get it looked at the right way.
