Leg Problems, Noninjury

Overview

Minor leg problems, such as sore muscles, are common. Leg problems often occur during sports or recreational activities, work-related tasks, and work or projects around the home. They also can be caused by injuries.

Leg problems may be minor or serious. They 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. That's 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 being too active or by the rapid growth of bone and muscle that occurs in children.

It may help you better understand leg problems if you know what the bones of the thighthigh and lower leglower leg look like, as well as the muscles and tendons. Leg problems that aren't related to a specific injury have many causes.

  • Problems can occur when you "overdo" an activity, do the same activity over and over again, or increase your exercise. This may be called an overuse injury, even though you didn't have an actual injury. Examples include bursitisbursitis, tendinitistendinitis, shin splintsshin splints, stress fracturesstress fractures, plantar fasciitisplantar fasciitis, and other muscle strains or tears. Muscle crampsMuscle cramps can be caused by activity or dehydrationdehydration, especially when you exercise in the heat.
  • Problems that affect the blood vessels (vascular disease) may include peripheral arterial diseaseperipheral arterial disease, inflammation of a vein (phlebitis), or a blood clot (thrombophlebitisthrombophlebitis).
    • A blood clot near the surface of the skin may cause only minor problems. But 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, also may increase your risk for blood clots. So can not being able to move a limb for a long time, such as when using a cast or splint.
    • Problems affecting the arteries (peripheral arterial disease) can cause cramping pain. It occurs with predictable amounts of exercise, such as walking a short distance, but it improves with rest.
  • Other diseases, such as osteoarthritisosteoarthritis, rheumatoid arthritisrheumatoid arthritis, and lupuslupus, can cause joint pain, stiffness, and swelling. A transient ischemic attack (TIA)transient ischemic attack (TIA) or a strokestroke 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 diseaseOsgood-Schlatter disease) and swelling and pain in the knee joint (juvenile idiopathic arthritisjuvenile idiopathic arthritis). Growing painsGrowing pains are common among fast-growing children and teens. Doctors don't know why children have growing pains. 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've been sitting or standing for long periods of time or during hot or humid weather. Sitting or lying down and propping up your legs will often relieve this type of swelling. Conditions that put increased pressure on the belly and pelvis, such as obesityobesity and pregnancy, also can cause swelling in the feet and ankles and varicose veinsvaricose veins.

  • Varicose veins can affect both men and women. They may cause a problem in only one leg.
  • The swelling in the feet and ankles that occurs during pregnancy usually gets worse toward the end of the pregnancy and goes away after the baby is born.

Many medicines can cause problems in the legs. For example, birth control pills and other hormones can increase your risk of blood clots. And water pills (diuretics), heart medicines, and cholesterol-lowering medicines (statins) can cause muscle cramps.

Some leg problems only occur at night.

  • Restless legs syndromeRestless legs syndrome causes an intense, often irresistible urge to move the legs. This can interrupt sleep and 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 give you short-term relief.
  • Nighttime leg cramps are a sudden tightening (contraction) of the leg muscles in the calf, thigh, or foot. They often occur just as you fall asleep or wake up. They can be painful. These cramps can last from a few seconds to a few minutes. Walking or stretching your leg can sometimes help relieve these cramps.

Most minor leg problems will heal on their own. Home treatment may be all that's needed. But serious leg problems also may occur. They need to be checked by a doctor soon.
