A stubborn ache under your toenail, the one that flares with every step or makes closed-toe shoes unbearable, may not be an ingrown nail at all. A small bony growth called a subungual exostosis can hide beneath the nail, pressing upward and causing pain that simple home care will never resolve. Getting a precise diagnosis is the first step toward lasting relief and a return to comfortable, confident movement.

What Is a Subungual Exostosis?
A subungual exostosis is a small bony prominence that forms in the bone beneath the toenail, most often the big toe. It typically develops after some form of trauma, such as stubbing the toe, repeated pressure from tight shoes, or a sports-related injury. As the bone grows, it can lift or distort the nail, creating ongoing pain and irritation.
Other small bone tumors, including osteochondromas and enchondromas, can also form in this area. Because each growth behaves differently, an accurate diagnosis through clinical examination and imaging is essential before treatment begins.
Common Symptoms to Watch For
- Persistent pain or throbbing under the toenail
- A nail that appears lifted, curved, or deformed
- Redness, swelling, or tenderness around the nail
- Pain that mimics an ingrown toenail but does not improve
- Discomfort with shoes, walking, or athletic activity
Diagnosis and Treatment Options
Your podiatrist will review your history, examine the toe, and order an X-ray to confirm the presence of a bony growth. Conservative steps such as roomier footwear, padding, and activity adjustments may ease mild symptoms. When pain persists or the nail becomes deformed, surgical removal of the spur is the most reliable solution.
The procedure is typically performed in the office under local anesthesia. After removal, the tissue is often sent to a pathologist to confirm the diagnosis, since osteochondromas and enchondromas can occasionally recur or require additional follow-up.
Recovery and Healing Support
Most patients return to light activity within a few days and full activity within several weeks. To accelerate healing and reduce inflammation, recovery may be supported with MLS laser therapy, an FDA-cleared treatment with an 85–90% efficacy rate for reducing pain and swelling.
