A pinched nerve is a compressed peripheral nerve, which can cause symptoms like numbness, tingling, and pain. This pain can be sharp and burning and can radiate outwards from one area of the body to another. For example, a pinched nerve in the lower back can cause symptoms in the hips, buttocks, or legs. This radiating pain is a distinguishing feature of a pinched nerve, as muscle strain usually causes localised pain. Pinched nerves can lead to muscle weakness, and in the case of cervical radiculopathy (a pinched nerve in the neck), it can also cause neck stiffness.

What You'll Learn
Pinched nerve vs strained muscle
A pinched nerve is a compressed peripheral nerve, which can be caused by the tissues, tendons, cartilage, muscles, or bones surrounding it. This compression can lead to abnormal sensations such as stinging, numbness, or weakness, along with pain that radiates along the nerve's path. For example, a pinched nerve in the lower back may cause pain that radiates down the leg, while one in the neck may cause pain in the shoulders or arms. Pinched nerves can often be treated with rest, anti-inflammatory medication, and physical therapy.
On the other hand, a strained or pulled muscle is caused by overstretching or tearing of the muscle or tendon, often due to overstraining during physical activity, improper form during workouts, or lifting heavy objects. A strained muscle typically causes soreness, a dull ache, stiffness, or tenderness in the affected area, along with reduced mobility and inflammation. Unlike pinched nerves, strained muscles usually do not cause weakness or numbness, and the pain is localized to the muscle itself. Strained muscles can often be treated with rest, ice, gentle stretching, and over-the-counter pain medication.
Both conditions can cause severe pain and limit mobility, but distinguishing between the two is crucial for receiving the correct treatment. For example, a pinched nerve may require physical therapy to address the underlying nerve compression, while a strained muscle may respond well to rest and anti-inflammatory medications.
It is important to seek professional evaluation if the pain is persistent, severe, or accompanied by numbness, weakness, or loss of function, as untreated pinched nerves can lead to long-term damage, including muscle weakness and nerve damage.

Pinched nerve symptoms
A pinched nerve is a broad term for a compressed peripheral nerve (the nerves outside of your brain and spinal cord). Tissues that surround your nerves — like bones, ligaments, and muscles — can put pressure on them and "squeeze" them. This typically causes symptoms like numbness, tingling, and pain.
Moderately to severely pinched nerves may result in muscle weakness. Since a single nerve can supply sensation to more than one part of your body, these symptoms can spread to different areas. For example, a pinched sciatic nerve in your lower back can cause symptoms in your hips, buttocks, and/or leg.
Pinched nerves along different parts of the spine result in different symptoms. Symptoms of a pinched nerve in the lower back include a sharp pain in the back that may travel to your foot, loss of reflexes in the lower part of your body, and numbness of the skin on the leg or foot, or the feeling that your foot has fallen asleep. Sciatica, which involves pain or muscle weakness in your lower back, hips, buttocks, legs, ankles, and feet, is another symptom of a pinched nerve in the lower back.

Pinched nerve causes
A pinched nerve is a compressed peripheral nerve, which can cause symptoms like numbness, tingling, and pain. Pinched nerves can be caused by surrounding tissues—such as bones, ligaments, and muscles—applying pressure to the nerve. Certain conditions can lead to abnormal pressure on nerves, including rheumatoid arthritis, osteoarthritis, bone spurs, injuries, herniated disks, spinal tumours, spinal stenosis, and spinal fractures. Age, obesity, and pregnancy can also increase the risk of experiencing a pinched nerve.
Pinched nerves can result in muscle weakness, with symptoms spreading to different areas of the body. For example, a pinched nerve in the lower back can cause symptoms in the hips, buttocks, or leg. This can lead to radiating pain, weakness, and numbness along the nerve's path. The pain associated with a pinched nerve is typically sharp and burning, extending from one area to another, whereas muscle strain pain is usually localized and dull.
Cervical radiculopathy, or a pinched nerve in the neck, can be caused by a herniated disk, which is more common in people up to 50 years old. Degenerative changes in the spine, such as cervical spondylosis, can also lead to cervical radiculopathy. This condition results in neck pain, stiffness, and neurological dysfunction caused by compression and inflammation of nerve roots in the cervical spine.
While a pulled muscle can sometimes feel similar to a pinched nerve, the pain associated with a pulled muscle typically does not radiate outward beyond the buttocks. Additionally, muscle strains usually do not cause tingling or numbness, whereas a pinched nerve often does. It is important to distinguish between a pinched nerve and a strained muscle to receive proper treatment.

Pinched nerve treatment
A pinched nerve occurs when a nerve is squeezed or compressed in a tight space in the body. This can cause pain, tingling, numbness, and weakness. The pressure can be caused by the surrounding tissues, muscles, tendons, or bones. Pinched nerves often occur in the neck or back and can be caused by specific injuries, overuse, or aging.
Treatment for a pinched nerve typically begins with conservative therapies and over-the-counter pain relievers such as ibuprofen or naproxen. It is recommended to remain physically active but to stop any movements that cause a spike in pain intensity. For a pinched nerve in the neck, a cervical collar and a cervical pillow may be suggested for brief periods. Physical therapy and strengthening exercises can also lead to faster pain relief. If the pain is severe, stronger medications such as oral corticosteroids may be prescribed. Anticonvulsant and antidepressant medications can also be effective in reducing nerve pain.
In most cases, pinched nerves will gradually resolve within four to six weeks with time and rest. However, if the pain persists or there is increasing difficulty with movement, surgery may be considered as a treatment option. Surgery is typically more invasive than other treatments and may involve procedures such as laminectomy or microdiscectomy.
To determine the appropriate treatment, it is important to identify the cause of the pinched nerve. This may involve consulting with a healthcare provider, undergoing a physical examination, and possibly imaging tests such as X-rays or MRI scans. Understanding the underlying cause can help develop an effective treatment plan, which may include specific exercises, medications, or surgical interventions.

Pinched nerve diagnosis
A pinched nerve is a broad term for a compressed peripheral nerve, which is any nerve outside of the spinal cord. It is not a technical medical diagnosis in itself, but rather a symptom of other conditions. Healthcare providers will diagnose more specific causes and consequences of pinched nerves, such as spinal stenosis, radiculopathy, or nerve entrapment.
Pinched nerves can be caused by surrounding tissues—like bones, ligaments, and muscles—applying pressure to the nerve. This can be due to injury, bone spurs, or an overgrowth of bone. Conditions such as rheumatoid arthritis and osteoarthritis can also lead to abnormal pressure on nerves. Other factors that increase the risk of experiencing a pinched nerve include age, obesity, pregnancy, and repetitive motion tasks.
The diagnosis of a pinched nerve typically involves a physical examination by a healthcare provider. They may examine the neck, shoulder, arms, and hands, looking for muscle weakness and changes in reflexes. The patient will be asked about the different sensations they are experiencing, as pinched nerves can cause numbness, tingling, and pain. The healthcare provider may also ask the patient to perform certain neck and arm movements to try to recreate or relieve their symptoms.
In the case of cervical radiculopathy, a type of pinched nerve in the neck, a herniated disk is often the cause. This is more common in people up to 50 years old. Cervical radiculopathy can be challenging to diagnose, as other neurological conditions can cause similar symptoms.
