What is a common sign of a bacterial infection in the nails?

A common sign of a bacterial infection in the nails is discoloration. This can manifest as a greenish or yellowish hue, which often results from the presence of the bacteria. This discoloration can occur due to bacterial growth, particularly when there is damage to the nail or surrounding tissue, allowing bacteria to infiltrate and multiply.

Pain, swelling, and peeling can also be associated with various nail and skin conditions, but discoloration is particularly indicative of a bacterial infection. The change in color is often one of the earliest and most noticeable symptoms, helping to distinguish it from other issues that might affect the nails. Recognizing this sign is crucial for early intervention and appropriate treatment of the infection.
