Blister - Blister symptom, treatment, causes
What is Blister ?
Blister is a collection of fluid under the surface layers of the skin. Blisters are caused by injury to the skin (fo example, a heel rubbed by an ill- fitting shoe), and by skin inflammation due to infection, burns, sunburn and other skin disorders. Blisters caused by skin or internal infections usually have specific diagnostic features, such as those of CHICKENPOX, HERPES SIMPLEX and SHINGLES. Small blood vessels in the base of a blister may rupture, making the blister fluid bloodstained (blood blister). In general, blisters should not be pricked because of the risk of introducing infection to underlying tissues. If blisters are large, troublesome. multiple, or appear without explanation, consult your doctor.
A blister or bulla is a defense mechanism of the human body. Blisters are quite common for anyone who regularly participates in sports. Blisters typically develop when their is friction and irritation to the surface layer of the skin and cause it to seperate from the second layer. If a blister is associated with sub-dermal bleeding, it may partially fill with blood, forming a blood blister. You get blisters most often on the soles of the feet and palms of the hands The hands and feet often rub against shoes, socks or sports equipment and create friction and these moist, warm conditions are perfect for blisters. The first sign of blisters will be redness over the skin, possibly at the back of the heel, the instep or toes. Blisters can occur from heat, frostbite, chemical injury, or friction. Unless infection occurs, blisters usually heal quickly. Blisters are a common problem with athletes wearing in new shoes as well as athletes or walkers who take part in exceptionally long events such as marathons or long hill walks. Blisters on the skin are called bullae. Bullae on the pleura (the membrane covering the lung) are also called blebs. Blistering also occurs as part of foodborne illness with Vibrio vulnificus ( seafood ). The best treatment is prevention: keep the substrate clean and dry, spot clean feces and urates as soon as you see them, and do thorough substrate changes regularly. One or two blisters can be treated safely at home.
