Peripheral Nerve Block

Peripheral nerve block is an injection of a local anesthetic and steroid medication into or near a peripheral nerve to prevent pain signals from reaching the brain. This pain management procedure can help those who suffer from neck pain ,low back pain, sciatica resulting from herniated discs, lumbar canal stenosis, complex regional pain syndrome (reflex sympathetic dystrophy), pain arising from peripheral vascular disease, shingles pain, myofascial pain syndrome or cancer pain.

Peripheral nerve blocks can be performed as a single injection, or series of injections. This procedure may relieve pain for several hours to several months. In many cases, peripheral nerve blocks are performed together with a rehabilitation program.


Possible side effects could be compared with common injection side effects, i.e. allergic reaction, bacterial infection, or bleeding in seldom cases. Steroid side effects are facial, eyes, arms, or legs swelling and elevated sugars for diabetic patients.

It is very important that the patient inform the physician about pregnancy or if he/she is taking blood thinning medication.
