What is overgrown hyponychium?

The hyponychium is the area beneath the fingernail or toenail's free edge. When the hyponychium becomes overgrown, it means that the skin and tissue under the nail have grown excessively. This can happen for a variety of reasons, including:

1. Fungal infections: Fungal infections of the nail can result in thickening and overgrowth of the hyponychium, along with other nail changes.
2. Trauma: Injuries to the nail or finger can cause the hyponychium to grow excessively as it tries to heal.
3. Psoriasis: Psoriasis is an autoimmune condition that can cause overgrowth of skin cells, including those under the nail.
4. Aging: As we age, our skin can become thinner and more susceptible to overgrowth.

Overgrown hyponychium can be unsightly and uncomfortable, causing pain and irritation. Treatment options include topical or oral antifungal medication, nail removal, or surgical removal of the excess tissue. It's important to consult a healthcare professional for guidance on the best course of treatment for your specific case.
