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 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 have
- Overuse injuries may occur when you "overdo" an
activity, do the same activity repeatedly, or increase your exercise. Examples
of overuse injuries include
stress fractures, or
Muscle cramps can be caused by activity or
dehydration, especially when you exercise in the heat. For more information, see the topic
- Problems that affect the
blood vessels (vascular disease) can include
peripheral arterial disease, inflammation of a vein
(phlebitis), or a blood clot (thrombophlebitis).
- A blood clot near the surface of the skin
may cause only minor problems, while a clot in a deep vein may be more serious.
Recent surgery, especially on bones or the pelvic or urinary organs, increases
the risk of blood clots, especially in deep leg veins. Prolonged bed rest and
inactivity, including sitting or standing in one position for long periods of
time, or prolonged immobilization of a limb, such as in a cast or splint, also
may increase the risk of blood clots.
- Problems affecting the
arteries (peripheral arterial disease) can cause cramping pain that occurs with
predictable amounts of exercise, such as walking a short distance, but improves
- Other diseases, such as
rheumatoid arthritis, and
lupus, can cause joint pain, stiffness, and swelling.
transient ischemic attack (TIA) or a
stroke can cause numbness, tingling, or loss of
function in one or both legs.
Some leg problems are seen only in children, such as swelling
at the top of the shinbone (Osgood-Schlatter disease) and swelling
and pain in the knee joint (juvenile idiopathic arthritis).
Growing pains are common among rapidly growing
children and teens and are probably caused by differences in growth rates
of muscle, bone, and soft tissue. These pains often last for 1 or 2 hours at a
time and can wake a child from sleep.
