From beginners to the pros, injuries from playing tennis do happen, especially in the wrist.
"There are about 18 million tennis players in the United States. And when we talk about injuries in the upper extremity, about 30% in tennis players are wrist injuries. That's a high number," says Dr. Sanj Kakar, a Mayo Clinic hand and wrist surgeon.
Many of those injuries are caused by chronic overuse.
"In the average tennis match, there are over 1,000 ground strokes. Now if you're practicing three, four times a week, for two, three hours, maybe not hit 1,000 shots. Maybe just practice on volleying," says Dr. Kakar.
