An epidural is a form of regional anesthesia using medication injected through a catheter placed into the spine. Epidural injections can cause a loss of sensation and a loss of pain by blocking the pain signals through nerves in or near the spinal cord.
Treating The Root Cause
Nerves that cause pain to a specific body part can be blocked with nerve-numbing medication injected into that part. This injection is called a nerve block. Different kinds of nerve blocks are used for different purposes.
A diagnostic nerve block helps find the source of pain. A therapeutic nerve block contains local anesthetic that can be used to control acute pain. Prognostic nerve blocks predict treatment results. And preemptive nerve blocks can prevent pain from a variety of conditions. Sometimes, nerve blocks can help the patient avoid surgery.
