Description
A friction blister is an area of skin that is raised and filled with clear liquid. They occur in areas where the skin has been rubbed aggressively (often the feet or hands). Minor damage to the skin underneath results in the accumulation of clear fluid and, if blood vessels are involved, bloody fluid. These blisters are called blood blisters.
Symptoms
One or more raised areas of skin with clear liquid inside appear on the skin. They are generally painful and appear in areas where friction is common.

Treatment
Friction blisters usually require no specific treatment and heal on their own within a few days. The skin provides a protective covering from infection. Therefore, blisters should be left intact. In the event that they break on their own, they should be gently cleaned with soap and water and bandaged with antibacterial ointment.
