Leg Problems, Noninjury Minor leg problems, such as sore
muscles, are common. Leg problems commonly occur during sports
or recreational activities, work-related tasks, and work or
projects around the home. Leg problems also can be caused by
injuries. If you think your leg problem is related to an injury,
see the topic Leg Injuries. Leg problems may be minor or serious
and may include symptoms such as pain, swelling, cramps,
numbness, tingling, weakness, or changes in temperature or
color. Symptoms often develop from exercise, everyday wear and
tear, or overuse. Older adults have a higher risk for leg
problems because they lose muscle mass as they age. Children may
have leg problems for the same reasons as adults or for reasons
specific to children. Problems are often caused by overactivity
or the rapid growth of bone and muscle that occurs in children.
It may be helpful to know the structure of the leg to better
understand leg problems. See pictures of: Leg problems that are
not related to a specific injury h
