The body is composed of various nerves with quite complex structures. Pinched nerves can occur anywhere in the body. The effects of this condition can be mild or even fatal.
Nerves run alongside surrounding tissues such as muscles, tendons, bones, blood vessels, and other tissues. Under certain conditions, these tissues can develop conditions such as displacement, enlargement, or inflammation, which can put pressure on the nerves. When pressure occurs on the nerves, this is called a pinched nerve. This condition can range from mild to fatal, depending on the degree of compression and the location of the nerve.
Causes of Pinched Nerves
As explained above, a pinched nerve occurs when pressure is exerted on surrounding tissue. Broadly speaking, the causes can be divided into two broad categories: internal and external. Internal causes are usually caused by conditions within the body.
For example, muscle tissue enlarges while the tissue is inelastic, leaving no more space, causing pressure on the nerve tissue. External causes, on the other hand, are usually caused by conditions outside the body. A common example is trauma or an accident involving a specific body part, which triggers pressure on the nerve tissue.
Symptom
The symptoms of a pinched nerve are greatly influenced by the location of the pinched nerve. However, in general, someone with a pinched nerve may experience tingling in the area it supplies. Additionally, people with a pinched nerve may experience pain. The intensity of the pain can vary greatly depending on the severity of the pinched nerve and its location.
If it's in a central area, the effects are usually more massive and severe. A pinched nerve can also affect muscle function in the area it supplies. Muscle function typically decreases and becomes weak. If this occurs over a long period of time, it's not uncommon for muscle volume to decrease, leading to muscle wasting or atrophy.
This decreased muscle function can make it difficult to move, disrupting daily activities. A pinched nerve can also experience numbness in the area it supplies. A burning sensation in the area is also common.
Risk Factors
There are many risk factors that can cause a pinched nerve, such as poor posture. Poor posture can put excessive pressure on nerve tissue, leading to a pinched nerve. Injury or trauma to a specific area of the body is also a common cause of pinched nerves, especially in young people. Repetitive work performed routinely in an awkward position, such as typing or lifting heavy objects, can lead to pinched nerves. The location of the injury or trauma can significantly affect the severity of symptoms and the prognosis.
Whether recovery is possible or whether it interferes with activity and can be fatal. In obese individuals, excess weight can increase the risk of pressure on nerve tissue, leading to a pinched nerve. A similar situation can occur during pregnancy due to changes in posture and an increased risk of nerve compression. Other diseases can also increase the risk of a pinched nerve, such as arthritis or joint inflammation.
This condition can cause inflammation in the surrounding area, leading to swelling and pressure on the nerve. A herniated nucleus pulposus in the spine can cause pressure on the central nervous system. In addition, tumors in various locations of the body, if they are large enough, can also cause pressure on the surrounding nerve tissue.
Diagnosis
A pinched nerve is not a diagnosis, but rather a condition that can occur due to underlying causes. Therefore, a comprehensive evaluation is essential to establish a definitive diagnosis and appropriate treatment to prevent potential complications.
Anamnesis
During the initial examination, the doctor will conduct a medical interview or history taking to determine the patient's symptoms. People with pinched nerves typically experience neuritis-like pain, which can include burning, numbness, and tingling in the affected area. The intensity of the pain can vary depending on the severity of the pinched nerve, its location, and the type of nerve involved. The pain can also radiate to other areas that may be innervated by the same nerve network.
The pain usually worsens with continued activity, which can increase pressure on the nerve network. Pain caused by pinched nerves is also typically difficult to improve with common pain relievers. This condition usually requires anti-inflammatory medication. If it persists for a long period of time and is not properly treated, the affected area of the body will experience decreased function and difficulty moving.
Physical examination
During the initial physical examination, the doctor will check vital signs such as blood pressure, pulse rate, respiratory rate, and body temperature. If the pinched nerve is a peripheral nerve, vital signs are usually not significantly affected. However, if the injury affects the central nervous system, particularly those affecting the respiratory system, respiratory rate and pulse rate can be significantly affected, resulting in abnormal results. A physical examination will then be performed on the area causing pain or other symptoms that require evaluation.
In cases of long-standing or chronic pinched nerves, muscle wasting or atrophy in the innervated area is usually present. The doctor will also perform a muscle strength test, a sensory examination of the affected area or areas experiencing symptoms, and a reflex test.
Supporting investigation
In some cases with typical symptoms, the doctor may immediately prescribe medication and schedule a follow-up visit for evaluation. However, if necessary, the doctor will recommend additional tests to confirm the diagnosis. In cases of pinched nerves in the central nervous system and surrounding areas, weakness can occur, which could be caused by other factors, such as electrolyte imbalances. Electrolyte tests are often performed to rule out this possibility. In cases of pinched nerves caused by trauma or accidents, an X-ray is often requested.
While not primarily used to assess the condition of the nerves, they can help determine whether there are bone or joint problems causing pressure on the nerve. If the treating doctor requires a more detailed examination, a CT scan may also be recommended in the area suspected of causing nerve compression. Another test that may be performed is electromyography, or EMG. This test is performed to assess for damage to nerve tissue.
Although rarely performed, an ultrasound can also be performed to assess the soft tissue surrounding the nerve that could be causing the pressure. Another test that may be performed is an MRI or magnetic resonance imaging. With this examination, the structure of the nerve tissue can be clearly seen and whether there is pressure or compression around it.
Therapy
Treatment for a pinched nerve depends on several factors, such as the location of the pinched nerve, its extent, the area it innervates, and the severity of the pinched nerve. The goal of therapy for a pinched nerve is to reduce pain, relieve pressure on the nerve, and restore function. In the initial stages, it's important to modify activities that can aggravate the pinched nerve, such as poor posture or lifting heavy objects.
Rest is essential to allow the nerve time to heal, or at least prevent further progression. Compresses can be applied to reduce inflammation and pain. The type of compress applied, whether hot or cold, depends on the underlying cause. In cases of trauma such as injury, cold compresses are usually applied. However, in other cases, warm compresses are often prescribed. To be sure, it's important to consult with your doctor.
The doctor will prescribe pain relievers and anti-inflammatories to reduce the symptoms of pain and inflammation that can arise from the pinched nerve. In addition to oral medications, in certain cases, doctors can also prescribe medication to reduce inflammation by injecting it into the area of the pinched nerve. Physiotherapy plays an important role in helping strengthen the muscles surrounding the nerve, increasing stability, and reducing the risk of muscle atrophy, which can affect motor function and strength.
Acupuncture therapy can also be an option for pinched nerves. However, for severe cases that do not improve with conservative methods, surgery may be an option. Surgical therapy can be performed by an orthopedic specialist or neurosurgeon, depending on the underlying cause and location of the pinched nerve. This therapy typically aims to relieve pressure on the nerve tissue by removing other compressive tissue, such as muscle or bone. Treatment options will vary depending on the patient's condition, underlying cause, location, and severity of the compressed nerve. It is important to consult with your treating physician.
Prevention
Maintaining a healthy lifestyle is crucial to maintain a healthy weight and reduce the risk of nerve compression. Furthermore, maintaining good posture during activities and work is crucial. When lifting heavy objects, pay attention to your position to avoid pain due to pinched nerves. Occupational therapy education can help provide appropriate information for daily activities and reduce the risk of pinched nerves.
Complications
If a pinched nerve is not properly treated over the long term, it can cause permanent nerve damage that is difficult to repair and restore normal function. The innervated area can experience decreased function, leading to muscle wasting or atrophy. Furthermore, permanent loss of function in the innervated area can also occur. This condition is particularly dangerous if it affects the central nervous system and surrounding areas. It often causes limb weakness and even paralysis.
Chronic pain can also be experienced if left untreated. Nerve pain, such as burning, numbness, and tingling, can be persistent and worsen if not treated properly. In addition to motor impairments, untreated pinched nerves can trigger sensory impairments, such as decreased tactile sensation and numbness. If a pinched nerve is in the central nervous system, specifically the spinal cord, it can cause problems with balance, coordination, and even respiratory function.
When to See a Doctor?
If you experience various symptoms typical of neuritis pain, such as burning, numbness, or tingling, accompanied by decreased sensory function, it is crucial to seek further evaluation from a doctor. If necessary, your doctor will refer you to a neurologist for further examination. At this stage, you will likely be given oral medication, physiotherapy, and regular follow-ups. If necessary, an anti-inflammatory injection will be administered to the affected area.
However, if the condition cannot be managed effectively with conservative therapy, the symptoms persist, or even worsen, causing complications, and surgery is necessary, your doctor may refer you to an orthopedic specialist or neurosurgeon. The choice of an orthopedic specialist or neurosurgeon is influenced by many factors, one of the main ones being the location of the injury. If the peripheral nerves are involved, it can usually be treated by an orthopedic specialist. For example, in cases of carpal tunnel syndrome (CTS), pressure on the nerve tissue occurs in the wrist area. Because the cavity in this area is rigid, pressure is placed on the nerve tissue.
Symptoms typically include numbness and tingling in the area innervated by the nerve. This is typically felt in the thumb, index finger, and half of the middle finger. People at high risk for this include those who frequently type for long periods and those who cook frequently, as repetitive wrist movements can trigger a pinched nerve. In these cases, conventional therapy can usually be used. However, surgery is sometimes necessary.
In cases of central nervous system surgery and the surrounding area, this is usually performed by a neurosurgeon. However, this is highly dependent on the doctor's discretion. For example, in cases of herniated nucleus pulposus (HNP), where pressure is placed on the nerves surrounding the spine, the symptoms are highly influenced by the location of the pinched nerve. The higher the location, the more severe the symptoms, as it can affect the underlying nerves.
If left untreated, HNP can lead to complications such as cauda equina syndrome and spinal cord compression, which can lead to bladder and bowel dysfunction. A herniated nucleus pulposus (HNP) in the neck can interfere with the respiratory system. It is crucial to perform an examination as early as possible so that appropriate treatment can be provided before complications, especially fatal ones, arise.
