Muscle Spasm In Back Of Thigh: Causes, Symptoms, And Treatment

Muscle cramps are a very common condition. It’s estimated that around 60 percent of adults experience muscle cramps occasionally, although they get more prevalent with age. It’s also worth mentioning that muscle cramps tend to occur more often in the legs, including the back of the thighs.

This is because the leg muscles are constantly in use and thus more prone to cramps. However, while muscle cramps often only last for a couple of seconds to a few minutes, the pain can be extremely intense. Additionally, although muscle cramps are typically harmless, they can sometimes indicate an underlying condition and should not be ignored.

Muscle Spasms In The Back Of Thigh

Muscle spasms that occur in the back of the thigh happen when a muscle suddenly contracts and causes pain or discomfort. A muscle spasm is sometimes known as a charley horse or a muscle cramp. Such spasms are generally caused by the overuse of your thigh muscles, dehydration, nutrient deficiency, and electrolyte imbalances. There are also several types of muscle spasms that you should be aware of.

Types Of Muscle Spasms

There are several types of muscle spasms. Some of these types of spasms are more serious than others. These are the three main types of muscle spasms you can experience:

  • Skeletal Muscle Spasms: This type of spasm is commonly caused by overexertion or dehydration. It typically manifests itself as a sudden, sharp pain. These types of spasms can occur in the back of the thigh.
  • Smooth Muscle Spasms: These occur in involuntary muscle groups, such as those found in the gut and bladder. They are usually caused by inflammation or irritation of the muscles.
  • Cardiac Muscle Spasms: These spasms occur in the heart muscle and can be very dangerous if left untreated. Cardiac muscle spasms are caused by a combination of factors, including high blood pressure, electrolyte imbalances, and certain medications.


Symptoms of Back of Thigh Muscle Spasm

There’s a good chance that you’ve experienced a muscle spasm before and therefore have a good idea of what it feels like. However, understanding the different symptoms of muscle spasms can help you identify them more quickly, thereby helping you determine if you need medical attention.

Most Common

Here are some of the common symptoms of muscle spasms in the back of the thigh:

  • Sudden And Intense Pain
  • Tightness Or Stiffness In The Affected Area
  • Inability To Move The Leg Or Walk Normally
  • Visible Twitching Or Jerking Of The Muscle
  • Swelling Or Tenderness In The Affected Area
  • Muscle Weakness

Less Common

There are a few symptoms that are much less common as far as cramping in the back of the thigh is concerned. These symptoms include

  • Numbness Or Tingling In The Affected Area
  • Muscle Cramping Or Knots
  • Limited Range Of Motion In The Leg
  • Difficulty Standing Or Sitting For Long Periods Of Time

Common Causes

Most of the time, muscle cramps in the back of the thigh result from minor causes that can be easily addressed. These common causes include the following:

  • Physical Exertion: Overexertion from physical activities, such as running or lifting weights, can cause the muscles to become fatigued and spasm. Simple rest and stretching exercises can fix this.
  • Dehydration: If you don’t drink enough water, it can result in dehydration, thereby increasing the risk of muscle spasms. Increasing your water intake and eating a well-balanced diet is usually enough to fix this issue.
  • Electrolyte Imbalance: Not having enough electrolytes can cause the muscles to become fatigued and spasm. Eating foods high in electrolytes, such as avocados and bananas, can help counteract this. IV therapy can also help if necessary.
  • Nerve Compressions: Nerves in the back of the thigh can become compressed, leading to muscle spasms. Depending on the compression’s severity, there are several ways to treat this issue. Sometimes, it will go away by itself with rest. Sometimes, treatment is required, whether it’s physical therapy or electrical stimulation.
  • Medications: Certain medications, such as diuretics or steroids, can cause muscle spasms.
  • Poor Posture: Poor posture can result in muscle imbalances, which can cause the muscles to spasm. Strengthening and stretching exercises can help counteract this.

Neurological Conditions Associated With Muscle Spasm In The Back Of Your Thigh

Although most muscle cramps in the back of the thigh are nothing to be concerned about and can be easily addressed, there are rare instances in which the spasms you’re experiencing may result from a neurological condition. These are the neurological disorders that can cause regular muscle spasms in the back of your thigh:

Peripheral Neuropathy

Peripheral neuropathy happens when the nerves in your body become damaged and begin to malfunction. This damage can cause pain, numbness, tingling, and muscle spasms in the affected areas of your body. There are several different causes of peripheral neuropathy, including diabetes and nerve compression.


Sciatica is a disorder that occurs when the sciatic nerve (a nerve that runs all the way down from the lower back to the legs) becomes irritated or compressed. This compression can cause pain, numbness, and muscle spasms in the affected area of your body. Sciatica can be caused by various conditions, including a herniated disc and spinal stenosis.

Piriformis Syndrome

Piriformis syndrome is a disorder that can develop when the piriformis muscle — which runs from your lower spine to your thigh bone — becomes irritated or inflamed. This irritation can cause pain, numbness, and muscle spasms in the area of the affected muscle. Piriformis syndrome can be caused by overuse, injury, or a muscle imbalance.

Spinal Stenosis

Spinal stenosis is a disorder that develops if the spinal canal narrows, thereby putting pressure on the nerve roots. This narrowing can cause pain, numbness, and muscle spasms. It’s important to note that spinal stenosis can be caused by various conditions, such as bone spurs or disc degeneration.

Lumbar Radiculopathy

Lumbar radiculopathy is when the nerve roots in your lower back become irritated or inflamed. This irritation can cause pain, numbness, and muscle spasms in the affected area of your body. Lumbar radiculopathy can be caused by spinal stenosis, herniated discs, or degenerative disc disease.

How Long Does A Spasm Last?

Most of the time, a muscle spasm in the back of the thigh shouldn’t last more than a few seconds to a couple of minutes at most. Factors that affect how long a spasm lasts include:

  • The Severity Of The Spasm: A more severe spasm typically lasts longer than a mild spasm.
  • The Cause Of The Spasm: If the spasm is caused by something more serious, such as a neurological condition, it may last longer.
  • Treatment: Treatment can help reduce the duration of the spasm in some cases.

It’s important to note that if the muscle spasms in the back of your thigh last more than a few minutes and you’re experiencing severe pain, you should seek medical attention.

When to See A Physician

If the muscle spasms in the back of your thigh are frequent, persistent, or severe, it’s essential to consult a doctor as quickly as possible. This is especially true if any efforts to address the muscle spasms you’re experiencing (such as by resting your legs and staying hydrated) have been unsuccessful. A physician should diagnose the underlying cause of your muscle spasms and suggest the best treatment option for you.

Diagnosis Of Muscle Spasms

Usually, the first thing a doctor will do is evaluate your medical history to determine if any existing conditions or medications that you’re taking could be contributing to your spasms. They will then do a physical exam.

During this exam, they will check for areas of tenderness, nerve irritation, and muscle weakness. Your doctor will likely ask you to perform specific tests and movements to assess your range of motion, strength, and flexibility.

Your doctor should also order an MRI or X-ray, to evaluate any underlying issues causing your muscle spasms.


Conventional Treatment Options

Conventional treatment options for muscle spasms in the back of the thigh will depend on the underlying cause. Most traditional doctors will recommend the following based on the severity of your muscle cramps:

Rest and Activity Modification

If your muscle spasms are mild, your doctor may suggest that you rest the affected leg and modify any activities that aggravate it. This may include taking breaks throughout your day, avoiding strenuous activities, and wearing comfortable shoes with good support.

Ice or Heat Therapy

Your doctor may also suggest applying either ice or heat to the affected area. Ice can help to reduce inflammation as well as relieve pain, while heat can help relax the affected area and promote healing.

Stretching and Gentle Exercises

Your doctor may also recommend stretching and gentle exercises to help reduce the frequency of muscle spasms by improving your flexibility and range of motion. They may also suggest strengthening exercises to help build up the muscles in your legs and reduce pain. Some of these exercises can include low-impact aerobic activities such as walking, swimming, or cycling.

Over-the-Counter Pain Relievers

Because muscle cramps can be painful, your doctor may suggest taking over-the-counter (OTC) pain relievers such as ibuprofen or acetaminophen. Certain OTC medications can also help reduce inflammation, which can help reduce the frequency of your muscle spasms. However, OTC medications only address the symptoms and not the underlying cause.

Massage Therapy

Your doctor may also recommend massage therapy to help reduce the pain and tension in the affected area. During a massage, your therapist will gently knead and work out the knots and tightness in your muscles, which can help relieve pain and improve flexibility.


In some cases, your doctor may suggest electrotherapy to help relax the affected muscles and reduce pain. This type of therapy involves sending electrical impulses through the affected area, which can help relax the muscles and relieve tension.
