Diffuse idiopathic skeletal hyperostosis (DISH).

A number of factors can contribute to the development of cervical stenosis, including: Spinal stenosis that occurs in the part of the spine that’s in your neck is called cervical spinal stenosis. Spinal stenosis that develops in the lower back causes a condition called lumbar stenosis, which is the most common kind of spinal stenosis. In some cases, this condition can affect both areas. Additionally this test can be ordered if the hand, arm, leg or foot numbness, tingling or weakness persists greater than 3 months with no relief from other therapies.Spinal stenosis can typically occur in one of two areas: your lower back or your neck. The test can be ordered after 1 month of symptoms of numbness, tingling, weakness in the hand/wrist/forearm where the symptoms are moderate to severe or persistent referred pain from the neck or forearm to hand is in your overall history with no relief from other therapies. Using this information, he or she will be able to make the best, accurate diagnosis of the underlying cause of your hand/wrist/forearm pain. Together, these various exams and tests, the EMG Test being the most specific and accurate test, will give your doctor a more complete picture of where your nerve is pinched and confirm are of dysfunction, inflammation and compression. Imaging studies DO NOT take the Place of Information discovered during an EMG Test.

That is why the EMG test is so very valuable. However it may not show minor nerve compression that often may be the cause of your symptoms. Your doctor may order a 3T (Tesla) MRI to observe the anatomical structures and to visually look for obstructions to nerve flow, called a pinched nerves or an impingement syndrome in your neck, back, shoulder, leg, foot, hand that may be causing your symptoms of numbness, tingling weakness or cold or heat sensation.

Frequent exposure of the nerve to cold, heat or vibration.

This is commonly seen in baseball shoulder movements.

Frequent flexion/extension or rotational movements of any joint, especially under a load.

Such is often seen in standing manufacturing jobs Prolonged standing on hard floors can cause the muscle to contract for prolonged periods of time leading to spasm and constant contraction of the muscle even at rest.

This can also occur with excessive extension of the gluteal muscles under a heavy load (heavy weight lifting). Piriformis syndrome is one such compression neuropathy. Frequent compression such as sitting on hard surfaces.What Causes Nerve Irritation, Inflammation or Compression?
