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 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 many causes.
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. 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 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.
Many 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) and heart medicines can cause muscle cramps.
Some leg problems are only present at night:
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 doctor.
Check your symptoms to decide if and when you should see a doctor.
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:

Symptoms of infection may include:
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.
Some medicines can cause leg problems. A few examples are:
Certain health conditions and medicines weaken the immune system's ability to fight off infection and illness. Some examples in adults are:
Based on your answers, you may need care right away. The problem is likely to get worse without medical care.
Based on your answers, you may need care soon. The problem probably will not get better without medical care.
Based on your answers, the problem may not improve without medical care.
Based on your answers, you need emergency care.
Call 911 or other emergency services now.
Sometimes people don't want to call 911. They may think that their symptoms aren't serious or that they can just get someone else to drive them. Or they might be concerned about the cost. But based on your answers, the safest and quickest way for you to get the care you need is to call 911 for medical transport to the hospital.
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.
Drink plenty of fluids. Sports drinks, such as Gatorade, will often help leg cramps. For more information about the home treatment of muscle cramps that are often caused by dehydration from exercise or heat, see the topic Dehydration.
If you think your child is having growing pains, try warmth and massage to relieve discomfort in the legs. Do not rub or massage a calf that is swollen.
For leg cramps, consider wearing support stockings during the day, and take frequent rest periods (with your feet up). If leg cramps occur during pregnancy, make sure you are eating a diet rich in calcium and magnesium. Talk with your doctor about taking a calcium supplement. He or she may recommend a calcium supplement that does not contain phosphorus.
Do not smoke. Smoking slows healing because it decreases blood supply and delays tissue repair. For more information, see the topic Quitting Smoking.
Try a non-prescription medicine to help treat your fever or pain:
Be sure to follow these safety tips when you use a non-prescription medicine:
Reduce stress on your leg (until you can get advice from your doctor):
