Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
Complex regional pain syndrome (CRPS Type 1 and Type 2), sometimes referred to by the hyponyms Reflex Sympathetic Dystrophy (RSD) or Reflex Neurovascular Dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.

Nerve decompressions are associated with a significant reduction in pain, in some cases the complete elimination of pain. [64] [58] [59] For patients with diabetic peripehral neuropathy (which affects 30% of diabetes patients [65]) and superimposed nerve compression, this may be treatable with multiple nerve decompressions.
A different study showed that out of 100 patients, 16% had an infectious event six weeks or less prior to the onset of neurological symptoms: seven patients had CIDP that was related to or followed viral hepatitis, and six had a chronic infection with the hepatitis B virus. The other nine patients had vague symptoms similar to the flu. [14]
However, a recent study using ultrasound to follow the spread of local anesthetic demonstrated an improved success rate of the block (relative to blocks done with nerve stimulator alone) even at the inferior roots of the plexus. [2] For supraclavicular block, nerve stimulation with a minimal threshold of 0.9 mA can offer a dependable block. [11]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
