A herniated disc is a condition in which the soft inner part of a spinal disc bulges out through a tear in the tough outer layer. This can put pressure on the nerves and cause pain, numbness, tingling, or weakness in the back, neck, arms, or legs. This pressure on the nerves can also cause muscle spasms, which are involuntary contractions of the muscles that can be painful and debilitating. In rare cases, a herniated disc can also cause propriospinal myoclonus (PSM), which is characterised by brief, involuntary twitching of a muscle or a group of muscles.

What You'll Learn

Herniated discs and muscle spasms
A herniated disc can cause muscle spasms, which are involuntary and sudden muscle contractions. These can be painful and limit movement, sleep, and daily activities. The pain can be intensified by coughing, sneezing, and bending.
Herniated discs occur when the soft inner part of a spinal disc bulges out through a tear in the tough outer layer. This can put pressure on the spinal cord and nearby nerves, causing pain, numbness, tingling, or weakness in the back, neck, arms, or legs. This pressure can also affect the nerves that control muscles, causing painful muscle contractions. The pain associated with a herniated disc can be intensified by inflammation, which induces nearby muscles to spasm in reaction to chemical irritants released from the leaking interior of the disc.
The most common sign of a herniated disc is lower back pain, which can be caused by nerve irritation, muscle spasm, or inflammation. This pain can lead to muscle spasms, and it can range from mild and dull to acute and severe. Herniated discs can also cause radiculopathy, a condition that results in abnormal nerve signaling and symptoms such as electric shock pain, tingling, numbness, and muscle weakness.
To manage the symptoms of a herniated disc, treatments such as medication, heat therapy, massage therapy, stretching exercises, and surgery can be used. Anti-inflammatory drugs can help reduce swelling and inflammation, while muscle relaxants can ease muscle spasms. Maintaining a healthy weight, exercising regularly, avoiding smoking, and practicing good posture can also help prevent and manage muscle spasms caused by herniated discs.
In some cases, surgery may be necessary to treat muscle spasms from a herniated disc. This involves removing part or all of the herniated disc to relieve pressure on the nerve and restore normal function. Minimally invasive surgery can reduce pressure on the spinal cord and stop the progression of symptoms.

Sciatica and herniated discs
A herniated disc is a condition in which the soft inner part of a spinal disc bulges out through a tear in the tough outer layer. This can put pressure on the nerves and cause pain, numbness, tingling, or weakness in the back, neck, arms, or legs. This pressure can also cause muscle spasms, which are involuntary contractions of the muscles that can be painful and debilitating. These spasms can occur in the muscles near the affected disc or in the muscles controlled by the compressed nerve.
Sciatica is a condition that can be caused by a herniated disc. It occurs when pressure is placed on the sciatic nerve, which runs from the lower spine down to the legs. This pressure can cause a range of symptoms, including burning, tingling, pain, and numbness. The pain typically begins in the lower back and moves through the buttocks and down the legs, sometimes even into the foot. It is usually felt on one side of the body, either the left or right. Sciatica can be managed through pain relief medications such as anti-inflammatory drugs and analgesics, muscle relaxants, and lifestyle changes.
The most common cause of herniated discs is age-related degradation, but other factors include obesity, trauma, excessive spin, and lack of conditioning. Maintaining a healthy weight, exercising regularly, avoiding smoking, practising good posture, and using proper lifting techniques can help prevent herniated discs and manage symptoms.
In most cases, herniated discs can be treated conservatively without surgery. This includes medication, heat therapy, massage therapy, stretching exercises, and cold therapy. However, if conservative treatments are ineffective, surgery may be considered as a last resort. Different types of surgery, such as discectomy, laminectomy, and spinal fusion, aim to relieve pressure on the nerve and restore normal function.

Radiculopathy and abnormal nerve signals
Radiculopathy is a condition that results in radiating pain, weakness, and/or numbness caused by compression or irritation of nerve roots in the spine. It can occur in the neck (cervical radiculopathy), upper middle back (thoracic radiculopathy), or lower back (lumbar radiculopathy). The symptoms of radiculopathy include pain, numbness, and tingling sensations around the affected nerve. In some cases, patients may experience muscle weakness and bowel or bladder problems.
Radiculopathy is often associated with abnormal nerve signals. When a nerve root in the spinal column is compressed or irritated, it can cause abnormal nerve signalling, leading to symptoms such as electric shock pains, tingling, numbness, and muscle weakness. These symptoms can vary depending on the location of the compressed nerve root. For example, cervical radiculopathy can cause pain and other symptoms in the neck that may radiate to the arms and hands, while lumbar radiculopathy can result in pain and numbness in the lower back that spreads to the legs.
A herniated disc is a common cause of radiculopathy. When a disc herniates, it can press against the spinal cord or nerves, leading to nerve compression and irritation. This can result in abnormal nerve signals, causing symptoms such as muscle spasms, cramping, and sharp, burning pain that may radiate from the lower back to the legs. The pain associated with a herniated disc can be intensified by inflammation, which induces nearby muscles to spasm in response to chemical irritants released from the disc.
The diagnosis and treatment of radiculopathy involve a combination of medical history, physical examination, and imaging techniques such as MRI, CT, and EMG scans. In most cases, radiculopathy can be managed with non-surgical treatments, including medication, cold therapy, and physical therapy exercises. However, in some cases, minimally invasive surgery may be recommended to reduce pressure on the spinal cord and improve symptoms.
It is important to note that the presence of a herniated disc does not always result in radiculopathy or muscle twitching. Some herniated discs may not press on any nerves, resulting in a lack of symptoms. Additionally, the symptoms of a herniated disc can vary depending on individual factors such as the size and location of the herniation, the patient's weight and fitness level, and other factors.

Treatment options for muscle spasms
Muscle spasms are involuntary and sudden muscle contractions that can cause severe pain and limit movement. They are often the result of small strains that build up in the spine over time. A herniated disc can cause muscle spasms by pressing on or irritating spinal nerves. This pressure or irritation can affect the nerves that control muscles, causing painful contractions.
Medication
Anti-inflammatory drugs such as ibuprofen can help reduce swelling and inflammation around nerve roots. Analgesics like paracetamol can also help control pain levels. Muscle relaxants can be used to ease muscle spasms, but they may cause drowsiness and sedation. Steroids like cortisone can be injected directly into the affected area to relieve pain and inflammation. Oral steroids may also be prescribed to control inflammation. It is important to note that medication is rarely a long-term solution and may lose effectiveness over time.
Physical Therapy
Physical therapy can help alleviate symptoms of a herniated disc. Techniques such as deep tissue massage can restore muscle mobility and provide relief from pain. Heat therapy increases blood circulation, flushing out substances that cause pain and spasms, while cold therapy restricts blood flow to reduce inflammation. Alternating between hot and cold therapies can be beneficial. The TENS procedure uses electric impulses to stimulate muscle tissue and relieve spasms and pain. Traction, a standard physical therapy practice, involves pulling bones apart to allow the prolapsed disc to slip back into place. Physical exercises to strengthen the core, improve flexibility, and strengthen muscles can help reduce pressure on the herniated disc, thereby alleviating symptoms.
Surgery
In some cases, surgery may be the only option for permanent relief. Minimally invasive surgery can reduce pressure on the spinal cord and stop the progression of symptoms. However, surgery is typically considered only when non-surgical treatments have failed to provide relief.

Preventing muscle spasms
Muscle spasms are involuntary and sudden muscle contractions. They can be painful and limit movement. A herniated disc can cause muscle spasms by pressing on the spinal nerves or irritating the nerves. This pressure or irritation can affect the nerves that control muscles, resulting in painful muscle contractions.
- Stay hydrated: Drink plenty of fluids, especially after intense exercise or working out in extreme heat. Electrolyte-enhanced beverages can be more effective than water in preventing muscle spasms.
- Proper nutrition: Consume foods rich in magnesium and potassium, such as leafy greens, bananas, or avocados. Carbohydrates are also important, as they are the primary fuel used during exercise.
- Wear comfortable shoes: If you know you'll be standing for a long time, wear supportive shoes like sneakers to help prevent muscle cramps.
- Adjust your sleep position: If you experience nighttime spasms, try using pillows to keep your toes pointed upward if you sleep on your back. If you sleep on your stomach, try hanging your feet over the end of the bed.
- Stay active: Take frequent movement breaks throughout the day to prevent muscles from stiffening.
- Stretching and massage: Regular stretching can help prevent muscle spasms, especially for muscles prone to spasms. Massage can also help.
- Physical therapy: A physical therapist can teach you specific stretching and strengthening exercises for the affected muscle(s).
- Medication: In severe cases, a healthcare provider may prescribe muscle relaxants to help ease symptoms. However, medication is usually not a long-term solution due to side effects.

Frequently asked questions
A herniated disc can cause muscle spasms, which are involuntary and sudden muscle contractions. These muscle contractions can be painful and debilitating. However, not all herniated discs will cause muscle spasms, and the presence of symptoms depends on whether the disc is pressing on a nerve.
The most common symptom of a herniated disc is lower back pain. This pain can be dull or severe and can be intensified by coughing, sneezing, or bending. Other symptoms include leg cramps, sciatica, weakness in the legs, and loss of leg function. In rare cases, there may be a loss of bowel or bladder control.
A herniated disc is usually diagnosed through a physical and neurological exam, including a review of the patient's medical history and pain management efforts. An X-ray may be required to rule out other causes, and a CT or MRI scan can determine the extent and position of disc damage.
Treatment for a herniated disc can include medication, heat therapy, massage therapy, stretching exercises, and surgery. In the first 24 to 48 hours, cold therapy can help reduce swelling, muscle spasms, and pain by decreasing blood flow.
