Temporary nerve blocks

Nerve blocks, usually with an injection through a tube or needle, can be temporary or long lasting (sometimes called permanent).

A temporary block uses a local anesthetic (numbing medicine) which lasts hours to days. In some situations, a corticosteroid may be added to treat inflammation in the area.

The medication can be put in one time by needle, or repeatedly if a tube is left in place.

Temporary blocks can be used to test whether a longer lasting block is likely to be helpful. They can also relieve pain from muscle spasms or temporary inflammations.

A common example of a temporary nerve block is a shot of novocaine at the dentist's office.
