When sciatica or other radiating nerve pain presents, can learning to distinguish between nerve pain and different types of pain help individuals recognize when spinal nerve roots are irritated or compressed or more serious problems that require medical attention?
Table of Contents
Spinal conditions such as herniated discs and stenosis can lead to radiating pain that travels down one arm or leg. Other symptoms include weakness, numbness, and/or shooting or burning electrical sensations. The medical term for pinched nerve symptoms is radiculopathy (National Institutes of Health: National Institute of Neurological Disorders and Stroke. 2020). Dermatomes could contribute to irritation in the spinal cord, where the nerve roots cause symptoms in the back and limbs.
The spinal cord has 31 segments.
Dermatomes are the body/skin areas with sensory input assigned to individual spinal nerves. Each nerve root has an associated dermatome, and various branches supply each dermatome off that single nerve root. Dermatomes are pathways through which sensational information in the skin transmits signals to and from the central nervous system. Sensations that are physically felt, like pressure and temperature, get transmitted to the central nervous system. When a spinal nerve root becomes compressed or irritated, usually because it comes into contact with another structure, it results in radiculopathy. (National Institutes of Health: National Institute of Neurological Disorders and Stroke. 2020).
Radiculopathy describes symptoms caused by a pinched nerve along the spine. Symptoms and sensations depend on where the nerve is pinched and the extent of the compression.
Part of a radiculopathy physical examination is testing the dermatomes for sensation. The practitioner will use specific manual tests to determine the spinal level from which the symptoms originate. Manual exams are often accompanied by diagnostic imaging tests like MRI, which can show abnormalities in the spinal nerve root. A complete physical examination will determine if the spinal nerve root is the source of the symptoms.
Many back disorders can be treated with conservative therapies to provide effective pain relief. For a herniated disk, for example, individuals may be recommended to rest and take a nonsteroidal anti-inflammatory medication. Acupuncture, physical therapy, chiropractic, non-surgical traction, or decompression therapies may also be prescribed. For severe pain, individuals may be offered an epidural steroid injection that can provide pain relief by reducing inflammation. (American Academy of Orthopaedic Surgeons: OrthoInfo. 2022) For spinal stenosis, a provider may first focus on physical therapy to improve overall fitness, strengthen the abdominals and back muscles, and preserve motion in the spine. Pain-relieving medications, including NSAIDs and corticosteroid injections, can reduce inflammation and relieve pain. (American College of Rheumatology. 2023) Physical therapists provide various therapies to decrease symptoms, including manual and mechanical decompression and traction. Surgery may be recommended for cases of radiculopathy that don’t respond to conservative treatments.
