Blisters can appear on the feet as a result of friction that occurs while wearing shoes or sandals. A blister may begin as a fluid-filled sac that is mostly painless. When the blister bursts it can ooze clear liquid and become painful. Treating foot blisters can usually be done at home, but frequent blistering or sores that appear infected should be treated by a health care professional.
Pierce the Blister
Draining the fluid from the blister can reduce pain and start the healing process. Continuing to walk or run with a blister that is full of fluid or blood can cause more pain. The friction that caused the blister can rub the top layer of skin off and deepen the wound. Instead, the blister can be pierced safely following a few simple steps. Individuals should cleanse the blister with rubbing alcohol and a cotton ball. A sharp needle should be disinfected with a clean cotton ball soaked in rubbing alcohol, as well. MayoClinic.com suggests puncturing the blister near the edge in several spots. Once several holes have been made, the fluid can be allowed to run out. This should be repeated twice more at 12-hour intervals, suggests MotherNature.com.
Protect the Ulcer
Whether the blister is popped by the individual or from regular foot movement, the ulcer, also called an open wound, should be protected from infection. This can be done by applying a thin layer of antibiotic ointment to the blister and covering it with a bandage or sterile gauze pad and medical tape.
Soaking the foot in bath of warm water and a generous handful of Epsom salts can encourage healing. Some stinging can result when the foot is immersed in the water. The foot should soak for 15 to 20 minutes once per day until the blister has healed. This remedy is also good for preventing future blisters by minimizing foot sweat, according to MotherNature.com. Individuals with sweating problems can use cornstarch, baby powder or other drying powders to absorb moisture and reduce friction. Drying agents can also reduce the pain associated with a healing blister.
