Nerve tension is pain that occurs because a nerve is being compressed or stuck in its surrounding tissue which prevents it from moving within its tract like it normally does. This can happen for a variety of reasons. If a joint has been immobile for a period of time it increases the risk that a nerve can get a little stuck.
A variety of disorders can compress a nerve resulting in the following neurological symptoms; Paraesthesia ( pins and needles), Numbness, Neuropathic pain, Weakness, Diminished Reflexes and sympathetic changes.
Muscular skeletal causes of nerve compression include swelling around the area, tightness of muscles, protrusion of vertebrae and degeneration of joints. In all cases, however, a nerve is compressed and this changes its function.
Most nerves can affect both sensory and motor symptoms, relatively common nerve compression syndromes causes are: Cervical Radiculopathy, Lumbar Radiculopathy, Thoracic outlet syndrome, Carpel Tinnel syndrome, or entrapment of the lateral femoral cutaneous nerve.
