Blood trapped under nails is a condition referred to as?

Blood trapped under nails is referred to as bruised nails. This condition occurs when trauma to the nail bed causes blood vessels to break and blood accumulates beneath the nail, leading to discoloration, often appearing as a dark spot or area under the nail. Bruised nails can be quite painful and may eventually lead to changes in the nail's growth or even loss if the injury is severe. Understanding this condition is important for recognizing nail health issues, especially for nail technicians who may encounter clients experiencing such symptoms.

In contrast, hangnails involve small tears of skin adjacent to the nail rather than blood under the nail. Nail fungus refers to infections caused by fungi that usually result in discoloration and thickening of the nail, not bleeding beneath it. Onychomycosis is a specific type of nail fungus infection that affects the nail's structure and appearance as well, but again, does not relate to blood accumulation under the nail.
