Blisters are quite common for anyone who on a regular basis participates in sports. Most athletes just believe them as the price you pay to play, but there are measures to avoid them, or decrease the pain and risk of infection if you find you have one.

Watch for a skin infection while your blister is curing. Signs of a skin infection include increased pain, swelling, redness, or warmth, red streaks extending away from the blister, a discharge of pus or a honey-colored fluid, fever, swollen glands. A skin infection is more likely if the dirt remains in a broken blister, cut, or scratch. The blister is in the genital or anal area, in a skin fold, or between the toes. You have a greater risk of infection and complications from a blister if you also have other conditions, such as diabetes, peripheral arterial disease, or immune system problems, which cause problems with healing. 

Causes

Blisters form when the skin rubs united with another surface, causing friction. First, a tear gets erupted within the upper layers of the skin forming a space between the layers while leaving the surface unbroken. Then the fluid seeps into the erupted area. Soles and palms are most often affected for several reasons. The hands and feet often rub aligned to shoes, skates, rackets, or other equipment. A blister usually requires thick and rather immobile epidermis, as is found in these areas. In addition to this, blisters form more simply on moist skin than on dry or soaked skin, and warm conditions help blister formation.

A cut or a scratch may turn into a blister-type sore that oozes a honey-colored fluid and forms a crust. This may be caused by impetigo, which most often develops on the face but can affect other parts of the body. Most broken blisters do not become infected if they are properly cleaned and cared for. Home treatment measures for cleaning and caring for a broken blister can reduce your risk of an infection. Call your health professional if you have a blister and signs of infection. A health professional can assess your symptoms and recommend the proper treatment. Prompt treatment of an infection can help prevent serious complications.

A blister is a bubble of fluid under the skin. The clear, watery liquid inside a blister is known to be a serum. It leaks in from neighboring tissues as a reaction to injured skin. If the blister remains unopened, serum can provide natural protection for the skin beneath it. Small blisters are called vesicles. Those larger than half an inch are called bullae. A blood blister is filled with blood, rather than serum.  Infections that cause blisters include bullous impetigo, an infection of the skin caused by staphylococci bacteria.  Viral infections of the lips and genital area due to the herpes simplex virus. Chickenpox and shingles are caused by the varicella zoster virus and coxsackievirus infections, which are more common in childhood.

Prevention

To prevent blisters, one requires minimizing the friction. For the feet, it begins with the appropriate shoe and sock selection. One should check out for more foot injuries for details. One should make sure that the shoes are the right size and shape. One should wear socks made from synthetic blends. And should before exercise, apply a petroleum jelly or talcum power to reduce friction, if required.

Blister Care

If one gets a blister, one will also want to relieve their pain, keep the blister from enlarging, and avoid infection. Signs of infection comprise pus draining from the blister, very red or warm skin around the blister, and red streaks leading away from the blister. Small, intact blisters that don't cause distress usually need no treatment. The best protection aligned with infection is a blister's own skin. Larger or painful blisters that are intact should be drained without removing the roof. Firstly one should clean the blister with rubbing alcohol or antibiotic soap and water. Then heat a straight pin or safety pin over a flame unless the pin glows red, and allow it to cool before puncturing a small hole at the edge of the blister. Then one should drain the fluid with gentle pressure, and then apply an antibiotic ointment such as bacitracin with polymyxin B (double antibiotic ointment) or bacitracin alone. One should avoid ointments that contain neomycin because they are more likely to cause an allergic reaction. Finally, one should cover the blister with a bandage. And most necessarily one should change the dressing daily.
