What are nerve blocks?

Nerve blocks with local anesthetics and/or other medications can be injected near various nerves in the body or near the spine as in epidural injections. Occasionally, Botox botulinum toxins can be injected in muscles to help with certain chronic pain conditions. It some conditions, implanted peripheral nerve stimulators or spinal cord stimulators may be helpful for severe intractable pain.

Often a group of nerves, called a plexus or ganglion, that causes pain to a specific organ or body region can be blocked with local anesthetics. If successful, another solution that numbs the nerves can then be injected. These injections (nerve blocks) will hopefully decrease the patient's needs to take oral pain medications.

A nerve block is a local anesthetic injected into or around a nerve or into the spine to temporarily prevent the nerve from relaying pain. A nerve block may cause temporary muscle paralysis or a loss of all feeling in the affected area or in the surrounding area.

Nerve blocks can be used to determine the source of pain, to treat painful conditions, and to predict how pain will respond to long-term treatments. Nerve blocks are also used for short-term pain relief after some surgeries and other procedures. They may be used for anesthesia during some smaller procedures, such as finger surgery.

A nerve block refers to an injection of medication into a nerve that connects with the painful area. Generally used for the purpose of giving anesthetic medication, it is commonly done for rib fractures. Blocks are also used to anesthetize an area for painless skin repair (suturing).

A nerve block is an injection that numbs a particular nerve to prevent pain signals from reaching your brain (much as lidocaine does in a dentist's office). It's effective for severe pain or for use during a surgical procedure.
