Thigh pain is a common problem that many people experience. It may come on suddenly or gradually, and it can cause you to have difficulty with normal functional mobility like walking, running, or climbing stairs. Sometimes thigh pain can occur after trauma or an injury, and other times it may come on for no apparent reason.
Anatomically speaking, your thigh is the area of your upper leg between your hip joint and your knee. Your quadriceps muscles reside in the front of your thigh and serve to bend your hip up and straighten your knee. Your hamstrings are in the back; these muscles help to bend your knee. Groin muscles on the inner aspect of your thigh pull your leg in, while your hip muscles, like the gluteus medius, pull your thigh out to the side. Several nerves travel down your thighs.
There are many different causes of thigh pain, some obvious and others not so much. Understanding your thigh pain and what may be causing it is the first step to properly treating your condition. Common causes of thigh pain may include:
Pinched Spinal Nerve
Thigh pain may be caused by a pinched spinal nerve. Herniated lumbar discs or low back arthritis may pinch on the nerves that exit your spinal column and travel down your thigh. Symptoms of a pinched nerve may include:
Pain in the front or back of your thigh
Numbness or tingling in your thigh
Weakness in your thigh muscles
Difficulty sitting or rising from sitting
Pinched nerves typically cause thigh pain that changes depending on your spine's position, so this can be a clue to your doctor that your low back is actually causing your thigh pain.
Spinal stenosis is a condition where your spinal nerves are compressed by the bony anatomy of your spine. Symptoms of stenosis include:
Pain in both thighs and legs
Numb and heavy feelings in your thighs
The pain from spinal stenosis is typically felt in both legs at the same time. Symptoms are made worse with standing walking and almost immediately relieved with sitting.
If you have any sort of traumatic event occur where your thigh is struck, this may cause pain. Usually, the cause of your thigh pain is obvious after trauma; your thigh was injured, and now it hurts. Symptoms from a blow to the thigh may include pain in the front or back of your thigh that is worse with activity. Bruising may be present. The pain is usually intermittent; it comes and goes depending on your activity level.
Quadriceps or Hamstring Tendonitis
Overuse and repetitive stress to your thigh muscles may cause inflammation in your tendons, a condition that is known as tendonitis. Symptoms of quad or hamstring tendonitis include:
Pain in the front or back of your thigh, usually near your knee or hip
Difficulty walking or climbing stairs due to pain
Weak feeling in your muscles in the front or back of your thigh
Symptoms usually last for four to six weeks and slowly get better with gentle exercise.
Iliotibial Band Friction Syndrome
Your iliotibial band is a thick piece of fascia and tissue that courses down the outer side of your thigh. Sometimes it can become irritated with overuse or repeated stress. This is a common running injury known as iliotibial band friction syndrome (ITBS). Symptoms of ITBS include:
Pain on the outside part of your thigh near your hip or knee
Tight feelings near your hip or knee
Difficulty walking or running
The pain from ITBS usually gets worse with increased activity and better with rest. Many people benefit from physical therapy to learn stretches and strengthening exercises for ITBS.
Sometimes, a cerebral vascular accident (CVA), also known as a stroke, can cause pain in your thigh. This is usually accompanied by numbness and tingling and a sudden onset of muscle weakness. This is a medical emergency, so if you suspect you have had a stroke, go to your local emergency department right away.
A blood clot in your lower leg or thigh may cause thigh pain. This is usually accompanied by warmth, swelling, and redness in your thigh. A blood clot needs to be diagnosed and managed immediately; if the clot dislodges from your vein, it can travel to your lungs and become an often fatal pulmonary embolism.
When to See a Doctor
Many people with thigh pain are able to treat it with no medical intervention. Sometimes, you need to see a doctor or medical professional for thigh pain. So how do you know when a doctor is necessary for your thigh pain?
In general, it is better to err on the side of caution. If you have thigh pain that you are unsure about or that does not subside with time and/or medication, see your doctor for a proper diagnosis.
Signs and symptoms that warrant a visit to a medical professional include:
Severe pain that limits your ability to function normally. If you are having difficulty walking normally due to your pain, visit your doctor.
Pain that is accompanied by fever or malaise. This could be a sign of infection, and your family doctor should check things out.
Thigh pain with redness, swelling, and warmth of your skin. This may be a sign of a blood clot and requires immediate medical attention.
Thigh pain that is accompanied by deformity. A muscle strain or tear may cause your thigh to look deformed, and a visit to an orthopedic surgeon may be needed to accurately diagnose and treat your condition.
Thigh pain that comes on suddenly and limits your ability to walk. A pinched nerve in your back may be the culprit here, and checking in with an orthopedist is recommended.
Most cases of thigh pain can be diagnosed accurately by your family physician or orthopedist. Some thigh pain that is caused by nerve compression or neurological conditions may require a neurologist to get an accurate diagnosis and treatment plan.
