What kind of doctor treats Leg Pain?
A primary care doctor or an orthopedic doctor, a specialist in bones, joints, and muscles, often evaluates leg pain. A vascular doctor, a specialist in blood vessels, may help if poor blood flow or a clot is the cause. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is leg pain?
Leg pain is a common problem. It can be due to a cramp, an injury, or another cause.
Symptoms
Some patterns doctors look for include:
- Aching pain in the legs that starts with walking or exercise and goes away after a few minutes of rest. This can point to poor blood flow.
- Warmth, redness, swelling, and tenderness, often in one leg. This can point to a blood clot.
- Numbness or tingling in the leg, or back pain along with the leg pain.
- Leg pain that continues at rest, skin that turns pale or blue, or sores that do not heal. These can be signs of peripheral artery disease.
Causes and who gets it
Muscle cramps are a common cause. Cramps can come from dehydration, low levels of potassium, sodium, calcium, or magnesium in the blood, and muscle fatigue from overuse. Some medicines, such as diuretics (water pills) and statins (cholesterol medicines), can also cause them.
An injury can also cause leg pain. Examples are a torn or overstretched muscle, a stress fracture (a hairline crack in a bone), tendinitis (an inflamed tendon), and shin splints (pain in the front of the leg from overuse).
Other common causes include:
- Peripheral artery disease (PAD), a narrowing of the arteries that lowers blood flow to the legs. People who smoke or have diabetes, high blood pressure, or high cholesterol are at higher risk.
- Deep vein thrombosis (DVT), a blood clot in a vein deep in the leg. It is most common in adults over age 60 but can happen at any age.
- Infection of the bone (osteomyelitis) or of the skin and soft tissue (cellulitis).
- Arthritis or gout, which inflame the leg joints.
- Neuropathy, or nerve damage, which is common in people with diabetes or heavy alcohol use.
- Varicose veins.
A less common cause is sciatic nerve pain from a slipped disk in the back.
How doctors diagnose it
Your provider will do a physical exam and look at your legs, feet, thighs, hips, back, knees, and ankles.
Tests depend on the suspected cause. For a possible clot, doctors often use a D-dimer blood test and a Doppler ultrasound, which uses sound waves to show blood flow. For possible PAD, doctors compare the blood pressure in your arm and your ankle (the ankle/brachial index).
Treatment
Treatment depends on the cause. If your leg pain is from cramps or overuse, you can take these steps first:
- Rest as much as possible.
- Raise your leg.
- Apply ice for up to 15 minutes, 4 times per day. Do this more often for the first few days.
- Gently stretch and massage cramping muscles.
- Take over-the-counter pain medicines such as acetaminophen or ibuprofen.
If medicines may be causing your leg pain, do not stop or change them without talking to your provider.
Other causes need other care. A DVT is treated with blood thinners, which keep more clots from forming or old ones from getting bigger. Most people take a blood thinner for at least 3 months, and these medicines make bleeding more likely. PAD care includes not smoking, regular exercise, and treating high blood pressure, high cholesterol, and diabetes.
When to see a doctor
Contact your health care provider if:
- Your painful leg is swollen or red.
- You have a fever.
- Your pain gets worse when you walk or exercise and improves with rest.
- Your leg pain does not go away, even at rest.
- You are taking medicines that may be causing leg pain.
- Self-care steps do not help.
Call 911 or go to the emergency room if your leg pain starts suddenly or gets suddenly worse, especially if the leg turns cold, pale, blue, or numb. Blocked blood flow can need treatment right away. Also call 911 or go to the emergency room if you have chest pain, coughing up blood, trouble breathing, or fainting. A clot that travels from the leg to the lungs can be fatal. Call 911 as well for sudden, severe pain anywhere in the body, or bleeding that will not stop.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either type of doctor can examine your leg, order first tests, and review your medicines. They can also refer you to a specialist.
Common questions
Can a blood clot cause leg pain?
Yes, a blood clot in a deep vein of the leg, called DVT, can cause leg pain. Other signs are swelling, redness, warmth, and tenderness, most often in one leg.
What causes leg cramps?
Leg cramps can come from dehydration, low levels of potassium, sodium, calcium, or magnesium in the blood, or muscle fatigue. Some medicines, such as diuretics and statins, can also cause cramps.
Can poor blood flow cause leg pain?
Yes, peripheral artery disease (PAD) can cause leg pain by lowering blood flow to the legs. The pain is usually felt when you walk or exercise and goes away with rest.
