Blisters are formed where the skin encounters physical friction. Such friction can be caused by footwear during running or skating or by other sporting apparatus such as that used in gymnastics, baseball, or racket events. Physical friction causes separation of the epidermis from the dermal layer of skin or separation within the multiple layers of the epidermis itself. Serum, lymph, blood, or extracellular fluid fills the space between layers. The fluid in blisters is clear, but bleeding into the blister occasionally occurs and causes red or blue discoloration. The usual complaints are pain, stinging, and sensitivity at the injury site.
Treatment of blisters is the same as for sunburn. One treatment session should be provided every day.
