Helps you check symptoms of leg problems not caused by injury. Covers symptoms like pain, swelling, cramps, numbness, tingling, weakness, and lumps and bumps under the skin. Includes pictures of bones of lower leg, thigh, and muscles and tendons.
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 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 what the bones of the thigh and lower leg look like as well as the muscles and tendons to better understand leg problems. Leg problems that are not related to a specific injury have
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
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.
Swollen feet are common
after you have been sitting or standing for long periods of time or during hot
or humid weather. Sitting or lying down and elevating your legs will often
relieve this type of swelling. Conditions that put increased pressure on the
belly and pelvis, such as
obesity and pregnancy, also can cause swelling in the
feet and ankles and
Varicose veins can affect both men and women and
may only cause a problem in one leg. For more information, see the topic
The swelling in the feet
and ankles that occurs during pregnancy usually gets worse toward the end of
the pregnancy and goes away after delivery. For more information, see the topic
medicines can cause problems in the legs. For example,
birth control pills and other hormones can increase your risk of blood clots,
while water pills (diuretics), heart medicines, and cholesterol-lowering
medicines (statins) can cause muscle cramps.
Some leg problems are
only present at night:
Restless legs syndrome causes an
intense, often irresistible urge to move the legs. This can interrupt sleep
make you overly tired during the day. You may have a "pins-and-needles,"
prickling, creeping, crawling, tingling, and sometimes painful feeling in your
legs. Moving your legs can provide short-term relief. For more information, see the topic Restless Legs Syndrome.
cramps are a sudden tightening (contraction) of the leg muscles in the calf,
thigh, or foot. They often occur just as you are falling asleep or waking up.
They can be painful and can last from a few seconds to a few minutes. Walking
or stretching your leg can sometimes help relieve nighttime leg cramps.
Most minor leg problems will heal on their own, and home
treatment may be all that is needed to relieve symptoms and promote healing.
But serious leg problems also may occur and require prompt evaluation by a

Pain in children 3 years and older
Severe pain (8 to 10): The pain
is so bad that the child can't stand it for more than a few hours, can't sleep,
and can't do anything else except focus on the pain. No one can tolerate severe
pain for more than a few hours.
Moderate pain (5 to 7): The pain is bad enough to disrupt the child's normal activities and
sleep, but the child can tolerate it for hours or days.
Mild pain (1 to 4): The child notices and may complain of the pain,
but it is not bad enough to disrupt his or her sleep or activities.
Pain in children under 3 years
It can be hard to tell how much pain a baby or toddler is in.
Severe pain (8 to 10): The
pain is so bad that the baby cannot sleep, cannot get comfortable, and cries
constantly no matter what you do. The baby may kick, make fists, or
Moderate pain (5 to 7): The baby is
very fussy, clings to you a lot, and may have trouble sleeping but responds
when you try to comfort him or her.
Mild pain (1 to 4): The baby is a little fussy and clings to you a little but responds
when you try to comfort him or her.
Some medicines can cause leg problems. A few examples

When an area turns blue, very pale, or cold, it can mean that there has been a sudden change in the blood
supply to the area. This can be serious.
There are other reasons
for color and temperature changes. Bruises often look blue. A limb may turn
blue or pale if you leave it in one position for too long, but its normal color
returns after you move it. What you are looking for is a change in how the area
looks (it turns blue or pale) and feels (it becomes cold to the touch), and
this change does not go away.
If your leg problem does not
require an evaluation by a doctor, you may be able to use home treatment to
help relieve pain, swelling, stiffness or muscle cramps.

Compression, or wrapping the
sore area with an elastic bandage (such as an Ace wrap), will help decrease
swelling. Don't wrap it too tightly, since this can cause more swelling below the
area. Loosen the bandage if it gets too tight. Signs that the bandage is too
tight include numbness, tingling, increased pain, coolness, or swelling in the
area below the bandage. Talk to your doctor if you think you need to use a wrap
for longer than 48 to 72 hours; a more serious problem may be

Exercise and stay active. It is best to do weight-bearing
exercise (such as walking, jogging, stair climbing, dancing, or lifting
weights) for 45 to 60 minutes at least 4 days a week. Weight-bearing exercises
stimulate new bone growth by working the muscles and bones against gravity.
Exercises that are not weight-bearing, such as swimming, are good for your
general health but do not stimulate new bone growth. Talk to your doctor about
an exercise program that is right for you. Begin slowly, especially if you have
been inactive. For more information, see the topic
