Lynn has been waking up each night with intense pain in her calves. She does not feel that it is serious enough to seek medical attention but would like to know what is causing the pain. What would you tell her concerning this problem? She has been playing tennis all summer for several hours each day. Could this have anything to do with the night pain?
What will be an ideal response?
Two things have occurred to Lauren while she was convalescing from her injury. First, the immobilization of the arm caused some muscle mass to atrophy. Second, the loss of muscle was replaced with tough connective tissue that locked her arm in place. With therapy the tissue can be stretched or torn enough to return the full range of motion.
