Why does my fingernail hurt when I press on it?

Pressing on a fingernail and experiencing pain may have various causes. Trauma is a common factor, such as compression or impact injuries, which can lead to soft tissue damage or capillary rupture, resulting in pain, redness, and swelling. Paronychia is another significant cause; damage to the fingernail, ingrown nails, or improper trimming may allow bacterial infection to develop, leading to paronychia. This condition manifests as pain upon pressing the nail, accompanied by symptoms such as redness, swelling, and tenderness. Other possible causes include Raynaud's syndrome, allergies, eczema, hangnails, and rheumatoid arthritis. To relieve and treat fingernail pain, it is recommended to seek medical attention promptly to identify the underlying cause and receive targeted treatment. Maintaining hand hygiene and avoiding excessive irritation can help prevent the occurrence of fingernail pain.
