The differential diagnosis includes a large number of diseases that affect the spinal cord. Neck or low back pain that radiates into your arms or legs is often a sign of impingement or pinching of a nerve as it emerges from your spinal cord. This pain is typically exacerbated by a recumbent position and may be related to secondary irritation or distention of the dura (43). Masks are required inside all of our care facilities, COVID-19 testing locations on Maryland.gov, Traumatic and Non-traumatic Spinal Cord Injury.

So I can research them to see if Im having other symptoms that go with whatever process is going on to cause it. Many causes of spinal cord compression cant be prevented. Medical care is focused on preventing further damage to the spinal cord and utilization of remaining function. Myelomalacia: Refers to increased T2 signal in the cord, BUT the cord is atrophic and gliotic as a result of a chronic injury of any form and is irreversible and the patient's symptoms will not improve. Spinal degeneration or injury to the facet joints are among the most common causes of chronic neck pain. This entity tends to affects the dorsal columns and lateral corticospinal tracts, hence patients present with paresthesia of the hands and feet with loss of proprioception, which may progress to gait ataxia and even ataxic paraplegia in severe cases (44). In addition to this, some studies have now described that the spinal cord can swell after surgery.
