What condition is characterized by a bacterial or fungal infection causing pain, redness, and possibly pus around the nail?

The condition characterized by a bacterial or fungal infection causing pain, redness, and possibly pus around the nail is paronychia. This condition occurs when the skin surrounding the nail becomes infected, often due to injury or the presence of moisture, which creates an environment conducive to microbial growth. Symptoms typically include swelling, tenderness, and the formation of pus, which can be quite painful.

Onychia refers specifically to an inflammation of the nail matrix, often linked to an infection that results in the detachment of the nail. Onychatrophia is a term for the wasting away or atrophy of the nail, which is not primarily an infection but more of a degenerative condition. Onychocryptosis, commonly known as an ingrown toenail, involves the nail growing into the surrounding skin, causing pain and inflammation but is not primarily due to a bacterial or fungal infection.

Understanding these conditions helps in identifying and differentiating between various nail disorders, ensuring appropriate treatment and care are provided.
