A pinched nerve is a non-medical term for a compressed nerve. It occurs when a nerve in the body is compressed or irritated by surrounding tissues, bones, muscles, or ligaments. This can cause pain, numbness, and a tingling sensation. In some cases, a pinched nerve can also lead to muscle weakness. This happens when the nerve is unable to transmit data to the brain, resulting in poor muscle performance. If left untreated, pinched nerves can cause long-term complications such as chronic pain and muscle atrophy.

What You'll Learn
Pinched nerve in the lower back
A pinched nerve in the lower back, also known as lumbar radiculopathy, is a compressed peripheral nerve outside of the spinal cord. It can cause symptoms like sharp pain, numbness, and tingling. In some cases, the pain may radiate down the leg. Sciatica is a common symptom of a pinched nerve in the lower back, characterised by pain, tingling, numbness, and weakness in the buttocks and the back of the legs.
There are several causes of a pinched nerve in the lower back. One common cause is a herniated disc, where the soft cushioning between the vertebrae bulges out and presses on nearby nerves. Spinal stenosis, a condition where the passage for nerve fibres in the spine narrows, can also lead to a pinched nerve. Other causes include injuries, genetic factors, and various medical conditions. Obesity, uneven posture, and age-related muscle weakness can also increase the risk of developing a pinched nerve.
To diagnose a pinched nerve, a doctor will perform a physical exam to assess your range of movement, reflexes, and the site of pain. They may also recommend imaging tests, such as a CT or MRI scan, to visualise the problem area. Treatment options depend on the nature of the pain and can include medication, physical therapy, and in severe cases, surgery.
To manage a pinched nerve in the lower back, it is recommended to avoid certain seated positions or activities that involve twisting or lifting, as they can aggravate the condition. Applying ice or heat for 20 minutes a few times a day can help reduce pain and muscle spasms. Maintaining a healthy weight and performing stretching exercises to strengthen the back and neck muscles can also help prevent and treat a pinched nerve.

Sciatica
A pinched nerve can cause muscle weakness, pain, and numbness. This occurs when the nerve is compressed or irritated, resulting in a "shutdown" of communication between the nerves and the brain.

Cervical radiculopathy
The main symptom of cervical radiculopathy is pain that spreads into the arm, neck, chest, upper back, and/or shoulders. This pain is usually felt on just one side of the body. Other symptoms include tingling or a "pins and needles" feeling, muscle weakness, and weakened reflexes. In terms of treatment, most cases of cervical radiculopathy go away with nonsurgical treatment, such as rest, medication, and physical therapy. However, in cases of significant nerve compression resulting in motor weakness, surgery may be necessary to relieve the pressure.

Pinched nerve and dizziness
A pinched nerve occurs when there is too much compression in a particular area due to surrounding tissues, bones, muscles, or tendons pressing against a nerve. This can cause a variety of symptoms, including pain, numbness, and tingling. While dizziness is not a common symptom, it can occur in certain cases, especially if the pinched nerve is located in the neck or upper spine.
The cervical spine, or neck, plays a crucial role in maintaining balance and head positioning. When a nerve in this area is pinched, it can disrupt the normal transmission of nerve signals to the brain, affecting balance and coordination. This disruption can lead to feelings of dizziness, imbalance, and vertigo-like symptoms. Additionally, the compression can put pressure on the nerves that control balance, further contributing to dizziness as a secondary symptom.
Cervicogenic dizziness is a condition linked to neck pain and cervical spine issues. It can cause dizziness, imbalance, and coordination issues. Cervical vertigo is another condition that can result from a pinched nerve in the cervical spine, leading to similar symptoms. These conditions can be differentiated from general dizziness, which can be caused by inner ear problems, low blood pressure, or migraines.
If you are experiencing dizziness along with other symptoms such as neck pain, numbness, or tingling, it is important to seek medical advice. A doctor can help diagnose the cause of your dizziness and recommend appropriate treatments, such as physical therapy, medication, or surgery. Early care is crucial to prevent further nerve damage and ensure optimal nerve function.
While some pinched nerves may heal on their own with rest, more severe cases may require additional treatments. These can include physical therapy, medication, or surgery. It is important to address the underlying cause and follow healthcare provider recommendations to effectively manage dizziness and other symptoms associated with a pinched nerve.

Pinched nerve treatment
A pinched nerve is a non-medical term for a compressed nerve. It occurs when a nerve is squeezed in a tight space in the body. This can happen when surrounding tissues, muscles, tendons, or bones place pressure on a nerve. Pinched nerves can cause pain, tingling, numbness, and muscle weakness.
If you suspect you have a pinched nerve, it is important to seek medical advice, especially if you experience intense pain or sudden muscle weakness. Your doctor will likely recommend conservative therapies to begin with. This may include over-the-counter pain relievers such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). It is important to remain physically active, but you should stop any movements that cause a spike in pain intensity. For a pinched nerve in the neck, your doctor may recommend using a cervical collar and a cervical pillow while you sleep.
Physical therapy, range-of-motion exercises, and strengthening exercises can also help manage pain and improve mobility. If the pain is severe, your doctor may prescribe stronger medications, such as oral corticosteroids or certain anticonvulsant and antidepressant medications that can reduce nerve pain.
In most cases, pinched nerves will gradually resolve within four to six weeks with conservative treatments. However, if the pain persists or if there is evidence of spinal cord compression, surgery may be considered as a last resort. One such surgical procedure is a laminectomy, which involves removing part or all of the back of the vertebrae and thickened tissue around it to create more room for the spinal cord and relieve pressure on the affected nerve.

Frequently asked questions
A pinched nerve refers to the compression of a nerve anywhere in the body, but they are especially common in the neck, lower back, and wrists. This compression can be caused by surrounding tissues, such as fluid, bones, muscles, or tendons, applying too much pressure.
Since nerve roots are "'mixed' nerves" that contain both sensory and motor functions, their compression can cause a range of motor issues, including impaired physical function and loss of strength in the upper limb. This can manifest as a loss of sensation to heat, touch, cold, and vibration, and a decrease in strength and range of motion.
If you have symptoms of a pinched nerve, such as muscle weakness, pain, or numbness, for more than a week and they are not improving with at-home care, you should see a healthcare provider. They can determine the underlying cause and recommend treatment.
