Radiculopathy is a condition due to a compressed nerve in the spine that can cause pain, numbness, tingling, or weakness along the course of the nerve. Radiculopathy can occur in any part of the spine, but it is most common in the lower back (lumbar radiculopathy) and in the neck (cervical radiculopathy). It is less commonly found in the middle portion of the spine (thoracic radiculopathy).
The symptoms of radiculopathy depend on which nerves are affected. The nerves exiting from the neck (cervical spine) control the muscles of the neck and arms and supply sensation there. The nerves from the middle portion of the back (thoracic spine) control the muscles of the chest and abdomen and supply sensation there. The nerves from the lower back (lumbar spine) control the muscles of the buttocks and legs and supply sensation there.
The most common symptoms of radiculopathy are pain, numbness and tingling in the arms or legs. It is common for patients to also have localized neck or back pain as well. Lumbar radiculopathy that causes pain that radiates down a lower extremity is commonly referred to as sciatica. Thoracic radiculopathy causes pain from the middle back that travels around to the chest. It is often mistaken for shingles.
Some patients develop a hypersensitivity to light touch that feels painful in the area involved. Less commonly, patients can develop weakness in the muscles controlled by the affected nerves. This is can indicate nerve damage.
Fortunately, most people can obtain good relief of their symptoms of radiculopathy with conservative treatment. This may include anti-inflammatory medications, physical therapy or chiropractic treatment, and avoiding activity that strains the neck or back. The majority of radiculopathy patients respond well to this conservative treatment, and symptoms often improve within six weeks to three months.
If patients do not improve with the treatments listed above they may benefit from an epidural steroid injection. With the help of an X-ray machine, a physician injects steroid medication between the bones of the spine adjacent to the involved nerves. This can help to rapidly reduce the inflammation and irritation of the nerve and help reduce the symptoms of radiculopathy.
In some cases the symptoms continue despite all of the above treatment options. If this occurs and the symptoms are severe, surgery may be an option.
