Did you know?

Tendinitis is often seen in active, healthy people who do something that requires repeated motion, including golfers and tennis players (especially those with improper form), carpenters, and violinists. It's usually treated by keeping the joint from moving, by means of a splint, cast, or bandage. If not dealt with in time, tendinitis can turn into the more serious tendinosis, or tendon degeneration.
