A Look At Nail Problems

Overview

Nails protect the tips of your fingers and toes. Problems with nails include changes in their color, shape, texture, or how they grow. These changes can be caused by injuries, infections, skin conditions, or other health issues. Most nail problems are not serious, but some need a doctor's care.

Yes. Nail problems are very common. Almost everyone will have a nail issue at some point, usually minor and temporary.

Nail problems can affect people of all ages, but some types are more common in older adults, people with diabetes, people who have damp hands or feet often, and those who bite their nails or wear tight shoes.

Symptoms

Common symptoms

• Discoloration — nails turn yellow, white, green, brown, or black
• Thickening or thinning of the nail
• Brittle, crumbly, or splitting nails
• Ridges or pits on the nail surface
• White spots or streaks
• Pain, swelling, or redness around the nail
• Nail separating from the nail bed
• A nail that curves downward or upward

Symptoms in children

• Bitten or chewed nails due to nervous habits
• Ingrown toenails from tight shoes or improper trimming
• Warts on or under the nail
• Nail changes after a minor injury from playing or sports

Symptoms in older adults

• Thicker, harder nails that are harder to trim
• Slow-growing nails
• Fungal infections that make nails yellow, thick, and brittle
• A higher chance of nail injury due to falls or pressure from footwear

Causes

Main causes

• Fungal or bacterial infections
• Injuries such as dropping something on the nail or slamming a finger in a door
• Skin conditions like psoriasis or eczema
• Repeated wetting or drying of hands and feet
• Aging — nails grow slower and become more brittle
• Certain health conditions that affect blood flow or immunity, such as diabetes

Risk factors

• Frequent exposure to water or harsh chemicals without gloves
• Tight-fitting shoes or high heels
• Frequently biting or picking at nails
• Nail polish or artificial nails that are left on for long periods
• Walking barefoot in public pools, locker rooms, or showers, which increases fungal infection risk
• Poor blood flow or a weakened immune system

When to see a doctor

See a doctor urgently if:

• You see redness, swelling, pus, or warmth around a nail, especially if you have diabetes or a weak immune system
• You have sudden, severe pain in or around a nail
• A nail becomes fully detached or very loose after an injury
• You have numbness or tingling beyond the finger or toe

Book a routine appointment if:

• A nail problem persists for more than a few weeks without improving
• You have an ingrown toenail that causes repeated pain or infection
• You notice dark streaks or unusual color changes in the nail that are not from bruising
• Your nails have changed shape, thickened, or crumbled over time
• You have symptoms even if they are mild but are worried about them

Diagnosis

A healthcare provider — usually a general practitioner or a skin specialist (dermatologist) — will ask about your symptoms, recent injuries, medical history, and lifestyle. They will examine your nails and the skin around them.

Tests that may be done

• A nail clipping that is sent to a laboratory for fungal culture or analysis
• Scraping skin debris from under the nail to check for infection
• A biopsy — a small sample of the nail or nail bed removed for testing, used in rare cases
• Blood tests if an underlying medical condition is suspected

What to expect at your appointment

The doctor will likely look at all of your nails and ask questions about how long you have noticed the problem. The appointment usually takes 10 to 15 minutes. If a sample is taken, it may not hurt much — just a small clip or scrape.

Treatment

Treatment for nail problems depends on the cause. For many issues, simple self-care is enough. For infections, the doctor may prescribe medications or recommend a procedure. Treatment is generally effective, though some nail infections take time and patience.

Self-care at home

• Keep your nails clean and totally dry.
• Trim nails straight across, and avoid cutting them too short.
• Use a moisturizing lotion or cream on your nails and cuticles.
• Wear gloves when doing dishes, cleaning, or gardening.
• Choose comfortable shoes that give your toes enough room.
• Avoid biting or picking at your nails, and do not remove the cuticle.
• Wear protective footwear in public showers, pools, and locker rooms.

Medical treatments

Your doctor may suggest prescription antifungal medicines (taken by mouth or applied to the nail) for fungal infections, antibiotic medicines for bacterial infections, or topical treatments for skin conditions affecting the nails. They may also advise removing a damaged or ingrown nail using a small surgical procedure. Talk to your healthcare provider about which approach is right for you, and always follow their instructions.

When is surgery considered?

Surgery is sometimes needed for an ingrown toenail that keeps coming back or for a severe infection. The procedure usually involves numbing the toe and removing a small part or the whole nail so the toe can heal. It is a minor procedure, but you will need aftercare to prevent recurrence.

Living with this condition

If you have a nail problem, keep your hands and feet clean and dry throughout the day. Check your nails regularly for changes, especially if you have diabetes. Be gentle with your nails — do not use metal tools to clean under them, and avoid aggressive buffing. Moisturize after washing your hands, and wear cotton socks and breathable shoes to keep feet dry.

Lifestyle tips

• Wear gloves for household chores and gardening.
• Use mild soap and avoid soaking nails for long periods.
• Trim nails after a shower or bath when they are softer.
• Avoid nail polish, gels, or artificial nails while treating a nail issue, unless your doctor says it is fine.
• Give nails regular 'breathers' without polish once in a while.

Diet and exercise

A balanced diet with enough protein, vitamins, and minerals helps nails grow stronger. Drinking water and staying active also improves blood flow, which supports nail health. There is no need for special supplements unless your doctor recommends them.

Mental health and emotional wellbeing

Nail problems can be embarrassing, especially when hands are visible. It is normal to feel self-conscious. Remember that most nail issues are treatable, and seeking help is the first step. If worry or shame affects your mood or daily life, talk to your doctor or a mental health professional.

Prevention

Many nail problems can be prevented with good hygiene and gentle nail care. Not all are preventable, but your habits make a big difference. Keep nails short, clean, and dry, and avoid sharing nail clippers or files.

Complications

If left untreated

• An infection may spread to the skin, deeper tissues, bones, or the bloodstream, especially in people with diabetes or weak immunity.
• A fungal infection may spread to other nails or to other parts of the body.
• Long-term nail damage such as permanent thickening, deformation, or loss of the nail can occur.
• Pain from an ingrown toenail may become worse and interfere with walking or daily activities.

Long-term outlook

The outlook for nail problems is generally good. Most nail conditions improve with simple self-care, medicines, or minor procedures. Even serious infections get better with the right treatment. Some changes may take months to fully resolve because nails grow slowly, but with patience, your nails can return to a healthier state. Your healthcare team is there to help you each step of the way.
