Ingrown Toenail in Tennis Players: Causes, Treatment & Safe Return to the Court

An ingrown toenail (onychocryptosis) can seem like a minor foot problem, but for tennis players it can become surprisingly painful. Every sprint, split step, lateral movement, and hard stop places pressure on the toes inside the tennis shoe.
When the edge of the toenail grows into the surrounding skin, it can cause pain, swelling, redness, inflammation, and sometimes infection. For competitive players, ignoring the problem can make ordinary court movement increasingly uncomfortable.
