What Are Common Causes of Leg Weakness?
There are a variety of reasons that a person might experience leg weakness. When a person has weakness in his or her legs, he or she might have numbness, might have problems walking and often might lose his or her balance while trying to walk. In some mild cases, it might be caused by a person sitting on his or her legs in an uncomfortable position for an extended period of time. Some of other common causes of leg weakness are migraine headaches, Graves’ disease, multiple sclerosis and back injuries. Migraines are classified as recurring severe headaches that might last for a couple of hours or several days. One of the signs of an oncoming migraine is numbness or weakness in the legs. The leg weakness might last for a short period of time, or it might last the entire time of the migraine. There are several factors, such as food or stress, that might trigger a migraine. It is not known why migraines affect some individuals more severely than others.
