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.
Nerve blocks can also be used therapeutically especially if combined with corticosteroids. [3] [8] [2] The relief from steroid injections is highly variable, with long-term, complete pain relief of approximately 22%. [8] The revision rate for injections is approximately 81% and a revision is likely to either be a repeat injection or a nerve ...

Injecting local pain relievers and steroids into the injured area alleviates intercostal nerve pain. [2] In this type of nerve block, a needle inserted between two ribs releases a steroid into the area around the nerve. The exact location of injection depends on the underlying cause of the injury.
CPN can be performed by percutaneous injection either anterior or posterior to the celiac plexus. [4] CPN is generally performed complementary to nerve blocks, due to the severe pain associated with the injection itself. Neurolysis is commonly performed only after a successful celiac plexus block. [4]
Pudendal anesthesia (pudendal nerve block, pudendal block or saddle block) is a form of local anesthesia. Pudendal anesthesia can be used to diagnose as well as treat illnesses. [ 1 ] A nerve block is the use of local anesthetic (e.g lidocaine ) to inhibit the sensation of pain caused by one or multiple nerves. [ 2 ]

Occipital nerve block is a procedure involving injection of steroids or anesthetics into regions of the greater occipital nerve and the lesser occipital nerve used to treat chronic headaches. These nerves are located in the back of the head near in the suboccipital triangle along the line between the inion and the mastoid process.
