Blisters in tennis players
For tennis players, the two most likely places for blisters to develop are the racket hand (hand and racket friction) and the feet (shoe, sock, and foot friction). Shoes that don’t fit properly, differences in court surfaces, heat, sweating, and an increased level of activity are all factors that could lead to the formation of blisters.
Part of the problem is that tennis players seldom stop playing when blisters begin to form, which results in a more severe problem. The early warning signs are red hot spots in the area affected and a stinging or burning sensation. Eventually, the skin area becomes white and swells with fluid, but it may or may not break.
Most blisters heal by themselves when the source of the friction is removed. If the top layer of skin stays intact, a doughnut-like pad placed over the top protects the skin and relieves the discomfort. The fluid can be drained if you have access to a sterile needle, but the overlying skin should be left as a protective dressing. If the skin has already been removed, treat the blistered area as you would an abrasion. Clean and rinse it with mild, soapy water or an antiseptic; then bandage it. Ask about over-the-counter medicated blister dressings at a pharmacy.
The best way to prevent a blister is to be aware of vulnerable areas and hot spots, and to take action to keep them from developing into blisters. Wearing a glove might protect the hand. Choosing shoes and socks that don’t irritate the skin might save the feet. Shop for socks that maintain their cushioning properties and wick moisture away from the skin. Apply creams to areas subject to chafing.
