Nerve Block

Anesthetic nerve blocks are a method used to treat and understand the source of nerve pain. A patient receives an injection of an anesthetic directly into a bundle of nerves. The injection prevents the nerves from sending pain signals to the brain, thus providing temporary pain relief. If the nerve block works, it may help identify affected nerves and lead to better pain treatment.

Two kinds of drugs used as nerve blocks are:

  • Lidocaine
  • Bupivacaine
