Radicular pain is caused by the root of a nerve.
Pressure on the nerve root can definitely cause pain and it may also cause sensory and/or motor deficits.
Lumbar disc hernias are commonly associated with sciatica (inflammation of the sciatic nerve in the lower back) due to disc protrusion or herniation that compresses the spinal nerve root radiating to the femoral or sciatic nerve.
Inflammation of a spinal nerve root is termed radiculitis.A nerve root injury is termed radiculopathy, a radiculopathy with an inflammatory component is termed radiculitis, and both radiculopathy and radiculitis may result in radicular pain which is pain that radiates in a dermatomal pattern innervated by that particular nerve root.
Radicular pain is caused by irritation of a nerve root. Sciatica is an example of radicular pain.
Compromise of a nerve root essentially means that the bones in the spine are pressing against a nerve in a manner that is not normal. This pressure typically results in pain.
Nerve root ectasia refers to the abnormal enlargement or dilation of a nerve root, typically occurring in the spinal column. This condition can result from various factors, including compression from adjacent structures, inflammation, or injury. Symptoms may include pain, numbness, or weakness in the areas served by the affected nerve root. Diagnosis is often confirmed through imaging studies such as MRI or CT scans.
The medical term for surgical resection of the dorsal root of a spinal nerve to relieve pain is rhizotomy.
I believe this hasn't been answered as it is a typo; they probably meant to write sciatic nerve, or ischiatic nerve is composed of L4-S3 spinal and anterior and posterior divisions of the lumbosacral plexus.
Compromise of a nerve root essentially means that the bones in the spine are pressing against a nerve in a manner that is not normal. This pressure typically results in pain.
A nerve root diverticula is an abnormal outpouching of the spinal nerve root sleeve, which is the covering of the nerve roots as they exit the spinal cord. This can sometimes cause irritation or compression of the nerve root, leading to symptoms such as radiating pain or weakness. Treatment may involve rest, physical therapy, or in some cases, surgery to relieve the pressure on the nerve.
An inflammation of the root of a spinal nerve is commonly referred to as a pinched nerve. This condition occurs when nearby tissues, such as bones, cartilage, or muscles, exert pressure on the nerve root, leading to pain, numbness, or weakness along the affected nerve's pathway. Pinched nerves can result from various factors, including herniated discs, arthritis, or injuries. Treatment often involves rest, physical therapy, or, in some cases, surgery to relieve the pressure on the nerve.
