2. Nerve block - Wikipedia

   en.wikipedia.org/wiki/Nerve_block

   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.

3. Neurolysis - Wikipedia

   en.wikipedia.org/wiki/Neurolysis

   Chemodenervation and nerve blocks are also associated with neurolysis. Additionally, there is external neurolysis. Peripheral nerves move (glide) across bones and muscles. A peripheral nerve can be trapped by scarring of surrounding tissue which may lead to potential nerve damage or pain.

4. Epidural steroid injection - Wikipedia

   en.wikipedia.org/wiki/Epidural_steroid_injection

   Epidural steroid injection for sciatica and spinal stenosis is of unclear effect. [1] The evidence to support use in the cervical spine is not very good. [3] When medical imaging is not used to determine the proper spot for injection, ESI benefits appear to be of short-term benefit when used in sciatica. [4]

5. Spinal anaesthesia - Wikipedia

   en.wikipedia.org/wiki/Spinal_anaesthesia

   Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.

   Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter.

7. Nerve decompression - Wikipedia

   en.wikipedia.org/wiki/Nerve_decompression

   Diagnostic nerve blocks can confirm the clinical diagnosis for chronic pain as well as identify the entrapment site. [5] A diagnostic block is like an inverted palpation in the sense that palpation will cause a sensory nerve to send a signal (action potential) and a block will prevent a sensory nerve from sending a signal. By blocking nerve ...
