One of the lasting effects of having a stroke is weakness in one side of the body. Fortunately for stroke victims and their families, it's possible to regain strength in this side. Doing so doesn't come automatically, however. If the stroke victim and those around him or her aren't dedicated to a treatment program, it's possible that the victim will never be able to use his or her arm on this side properly again.

If you suffer pain or sensitivity in both or one of your knees that does not stop after a short period, you may be suffering from chronic knee pain. Chronic knee pain may not be traceable to one single incident; some of the most common causes include tendinitis, a torn ligament, arthritis, a tumor, or a Baker's cyst. It's possible for chronic knee pain to interfere with your quality of life, making it difficult for you to enjoy the activities you love.
