Toenails and Calluses: Managing Ingrown Nails, Thick Nails, and Hard Skin
By Dr. Kayla Wright, DPM · 4 min read
Toenail and skin problems are among the most common reasons people see a podiatrist, and among the most satisfying to fix, because relief is often quick. But they're also the problems people most often try to solve at home, sometimes making things worse. Here's how to manage the common ones safely and know when to get help.
Ingrown toenails
An ingrown toenail happens when the edge of the nail grows into the surrounding skin, causing pain, redness, swelling, and sometimes infection. They're one of the most common nail problems, most often affecting the big toe and most common in teenagers and young adults.
What helps mild cases: warm soaks, keeping the area clean, and wearing roomy footwear that doesn't press on the toe. Well-fitting shoes matter here, our shoes and orthotics guide covers footwear that gives your toes room.
What to avoid: repeatedly digging at the nail or attempting "bathroom surgery," which often worsens inflammation and infection.
When it's recurrent or infected: this is where professional care shines. For nails that keep coming back, a minor in-office procedure that removes the offending nail border, often with a chemical (phenol) treatment of the nail matrix, is highly effective. Systematic-review and meta-analysis evidence shows that phenol-based treatment of the nail matrix is associated with meaningfully lower recurrence rates compared with other methods, and it's considered a preferred approach for more advanced ingrown nails. It's a quick procedure with a high success rate.
Thickened or discolored nails
Nails can thicken or discolor from fungal infection, repetitive trauma (common in runners and athletes), or other causes. Because the causes differ, so do the treatments, and getting the diagnosis right matters. Thickened nails from a jammed or repeatedly bumped toe are managed differently from a true fungal infection. A podiatrist can determine which you have and outline realistic options, since some nail conditions are stubborn and expectations should be set honestly.
Corns and calluses
Corns and calluses are areas of thickened skin that form in response to pressure and friction. They're protective by nature, but when they become painful, they're signaling that something is concentrating pressure in that spot.
The key insight: calluses are usually a symptom, not the root problem. They often form because of footwear that doesn't fit, a bony prominence, or a deformity like a bunion or hammertoe that changes how pressure distributes. Simply shaving the callus without addressing the pressure source means it comes right back.
What helps: properly fitting footwear, cushioning or padding, and addressing the underlying pressure point. A podiatrist can safely reduce painful calluses and, more importantly, identify and address why they're forming.
What to avoid: medicated corn-removal products can be risky, particularly for anyone with diabetes or poor circulation, and aggressive at-home cutting can cause wounds and infection.
A special note on diabetes and circulation
If you have diabetes or poor circulation, toenail and skin problems deserve extra caution. What's a minor nuisance for one person can become a serious wound for another. In these cases, routine professional foot care isn't cosmetic, it's preventive medicine. Please don't self-treat ingrown nails, calluses, or corns; have them managed professionally.
When to see a podiatrist
Seek care if you have:
- An ingrown nail that's infected or keeps recurring
- A painful corn or callus that won't resolve
- Thickened or discolored nails you'd like evaluated
- Any nail or skin issue and diabetes or circulation problems
