Is there a medical term/explanation for the following injury?

Degenerative Disc Disease

As we age, the discs in our back lose water content and begin to break down. They become stiff and flatten, losing their ability to act as shock absorbers. The end result of this is that the surrounding anatomy begins to see increased load and ultimately becomes arthritic. As the normal anatomy becomes distorted, this can also lead to instability in the spine. Unstable vertebrae can slip back and forth irritating the nearby nerves (this is called degenerative lumbar spondylolisthesis).

Spondylolysis

Spondylolysis is a fracture or defect of the pars interarticularis, an area of the bone in the posterior vertebra. It most commonly occurs at the L5 vertebra. This condition is thought to be due to a stress fracture and is common in female gymnasts, power weight lifters, rowers, and football linemen.

The C8 spinal nerve allows the brain to send motor controls for muscle movements. The C8 nerve helps control the hands, including finger flexion (handgrip) and the forearm.

The pain can vary widely, from a mild ache to a sharp, burning sensation or excruciating pain. Sometimes it can feel like a jolt or electric shock. It can be worse when you cough or sneeze, and prolonged sitting can aggravate symptoms. Usually only one side of your body is affected.Sep 26, 2019
