Hi,
Blood blisters are caused by a rupture of the blood vessels underneath the skin’s surface. This rupture is usually caused by some form of trauma, scald, allergic irritants, viral skin infections, and fungal skin infections. For the most part, blood blisters do not require special medical attention. However, if it is severe or reappears, have this evaluated further for proper management. Try to avoid popping the blister to prevent secondary infection and this can also slow down the body’s natural healing process. Take care and regards.
