A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
' pain receptor ') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals [1] [2] [3] to the spinal cord and the brain. The brain creates the sensation of pain to direct attention to the body part, so the threat can be mitigated; this process is called nociception.
Central pain syndrome, also known as central neuropathic pain, [1] is a neurological condition consisting of constant moderate to severe pain due to damage to the central nervous system (CNS) which causes a sensitization of the pain system. [2] [3] The extent of pain and the areas affected are related to the cause of the injury. [4]
Compression of nerves can occur because of a tumour mass or injury. Alternatively, if a nerve is in an area with a fixed size it may be trapped if the other components increase in size, such as carpal tunnel syndrome and tarsal tunnel syndrome. Common symptoms of carpal tunnel syndrome include pain and numbness in the thumb, index and middle ...
The gate control theory of pain asserts that non-painful input closes the nerve "gates" to painful input, which prevents pain sensation from traveling to the central nervous system. In the top panel, the nonnociceptive, large-diameter sensory fiber (orange) is more active than the nociceptive small-diameter fiber (blue), therefore the net input ...
Area of the human body surface innervated by each spinal nerve. Even mammals, including humans, show the segmented bilaterian body plan at the level of the nervous system. The spinal cord contains a series of segmental ganglia, each giving rise to motor and sensory nerves that innervate a portion of the body surface and underlying musculature.
The cause is believed to be muscle tension or spasms within the affected musculature. [1] Diagnosis is based on the symptoms and possible sleep studies. [1] Treatment may include pain medication, physical therapy, mouth guards, and occasionally benzodiazepine. [1] It is a relatively common cause of temporomandibular pain. [1]
Polyneuropathy (from Greek poly- ' many ' neuro- ' nerve ' and -pathy ' sickness ') is damage or disease affecting peripheral nerves (peripheral neuropathy) in roughly the same areas on both sides of the body, featuring weakness, numbness, and burning pain. [1]
