What could be the reasons for persistent toenail pain?

There are several reasons why you might have ongoing pain in your toenail. One common cause is an ingrown toenail, where the corner of the nail digs into the skin, causing pain, redness, and sometimes pus. An infection, such as paronychia, can also make the area painful; this happens when germs enter near or under the nail, leading to swelling and tenderness. Sometimes, repeated minor injuries or trauma to the nail can cause persistent pain. For older people, changes in the nail due to age can also lead to discomfort, as the nails may become thicker, more brittle, or develop a fungal infection like onychomycosis. In these cases, the nail can become misshapen and painful due to pressure from shoes or walking. It is important to watch for signs of swelling, redness, or changes in how the nail looks. If the pain continues or gets worse, you can check your symptoms to help identify possible causes and determine whether you should seek medical attention.
