Understanding Ingrown Toenails: Causes & Symptoms
Podiatrist Review
What You Need to Know About Ingrown Toenails
An ingrown toenail, known clinically as onychocryptosis, is a common foot condition where the edge of the nail presses into the adjacent skin fold.
While it most commonly affects the big toe, an ingrown nail can develop on any toe, starting with mild discomfort before escalating to severe pain and potential infection.
How Ingrown Toenails Develop
Initially, an ingrown toenail may present as mild tenderness or pressure along the side of the nail fold (the sulcus). As the nail grows longer and curves into the skin, it can penetrate the surrounding soft tissue. Once the skin barrier is broken, localized redness, swelling, and sharper pain develop, creating an entry point for bacteria and increasing the risk of infection.
Common Causes and Risk Factors
Ingrown nails are frequently triggered by daily habits or environmental conditions affecting the feet. Poor nail trimming techniques and tight footwear that compresses the toes are two of the most frequent triggers, placing excess lateral pressure on the toe tissue.
Key Contributing Factors
- Incorrect nail trimming, such as cutting nails too short or rounding down into the corners.
- Tight or narrow shoes that squeeze the toes together.
- Excessive sweating (hyperhidrosis), which softens the skin fold surrounding the nail.
- Trauma or direct injury to the toe altering normal nail growth.
Support Your Feet with Proper Footwear
Preventing unnecessary pressure on your toes starts with well-fitting footwear that gives your feet room to move naturally.
