Tennis is a fun and inexpensive sport that is easily accessible living in the city as there are numerous free tennis courts throughout Chicago.  There are also many tennis/racquet clubs that are great for finding competitive players or for getting lessons. 

One of the more common complaints from a tennis player is elbow and forearm pain, more commonly known as "tennis elbow".  The forearm flexor muscles can also become a problem for those players with an aggressive forehand shot. 

Shoulder injuries can also become a problem.  Problems with the rotator cuff muscles can arise from improper stresses on the shoulder created particularly during the serve.  A biomechanical evaluation would be necessary to evaluate the cause of the injury.

Ankle injuries can be a common problem due to the quick changes in direction.   An inversion ankle sprains is the most common of these injuries.
