A blood blister under the nail, also known as a subungual hematoma, is a common condition characterized by the accumulation of blood beneath the nail plate. This condition often results from trauma or injury to the finger or toe, causing pain, swelling, and discoloration of the affected area. Understanding the causes and treatment options for a blood blister under the nail is essential for effective management and prevention of complications.
The formation of a blood blister under the nail typically occurs when a blood vessel beneath the nail is damaged, leading to bleeding into the confined space. This can happen due to various reasons, including repetitive trauma, ill-fitting footwear, or accidental injuries. In some cases, a blood blister under the nail may also be a sign of an underlying medical condition, such as a blood clotting disorder or a fungal infection.
