Blisters are usually caused by damage to the skin, by physical damage or infection or illness. Generally, blisters can be self-treated and do not usually require medical attention. Blisters occur when the epidermis, which is the upper layer of skin, tears away from the layer underneath and fluid collects in the space to create a blister. Blisters are caused by friction, skin reaction or medical conditions. Friction blisters are common with poorly fitting shoes, manual work, sports and outdoor pursuits. As the skin is rubbed the blister forms, which can be painful and uncomfortable. Blisters caused by skin reactions or when the skin is exposed to excessive heat like burns or sunburn, it can also be when your skin comes into contact with some chemicals. There are many medical conditions where blisters can occur, like chicken pox, cold sores and other hand and foot or mouth diseases. Blisters can be painful and the sooner you treat them, the better the outcome. The treatment for a blister is to protect the blister using a plaster or a special blister dressing. Do not burst the blister, as the blister is there to protect the skin, so if you burst it you'll expose the unprotected skin, which can cause infection and further damage. The blister will slowly reduce as the body absorbs the fluid and the blister will eventually fall off. If a blister has burst, allow the fluid to drain out, wash with water and cover the blister with a sterile dressing. You need to see a doctor or a nurse if the blister is very painful, it gets infected, you keep getting new blisters or the blisters are caused by sunburn, burns or scalds or an allergic reaction. In these cases, antibiotics are sometimes used to treat the infection. Blood blisters should also be left to heal naturally. If the blood blister is painful, use an ice pack for 10 to 30 minutes, which may help, but be careful not to burn the skin with the cold. Finally, prevention is better than cure, so make sure your feet are dry and you have good fitting shoes. If you play sports or exercise regularly, wear thicker wool socks and avoid new shoes that are not broken in. Gloves will also protect your hands against blisters.
