Should I puncture this blister? This question is frequently asked by patients and runners. It is always best to have a physician make the ultimate decision, but a majority of blisters can be released to allow the fluid to drain and lead to a faster and less painful recovery. A blister is secondary to friction which disrupts the layers of skin allowing fluid to accumulate. When access fluid is present and the skin is unable to stretch, this can become very painful. Using a sterile instrument such as manicure scissors, or even a needle (always wipe with alcohol) the blister can be broken allowing the fluid to drain from a gravity dependent area on the blister. Blisters can also result from fractures or even peripheral vascular disease. These are medical emergencies and require immediate attention.
