Nerve Injections
There are innumerable nerves in your body, and pain may stem from any one of them. We can use injection of an anesthetic (numbing) agent to eliminate pain sensation in the affected area. These numbing medications can be used on any part of the nervous system and on any nerve fiber type. The block affects the area of injection but also spreads along the nerve. The benefit of such an injection is that it gives good diagnostic information (ie if the pain decreases, we can be confident that your pain was generated from the targeted nerve).
The main types of nerve injections are:
- Axial nerve injections – target the nerves exiting the spinal column in the neck and low back. In addition to epidural steroid injections and medial branch blocks, some common nerve injections include:
- Sympathetic blocks – targets the sympathetic nerves that come off the larger nerve roots. These are useful in treating CRPS and PTSD
- Selective nerve root blocks – targets the nerve roots as they exit the spine. These are very similar to ESIs but typically only use numbing medication to yield the highest possible diagnostic benefit.
- Peripheral nerve injections – target various nerves anywhere outside of the spinal area
- Genicular nerve injections – target nerves that go to your knee
- Lateral Femoral Cutaneous nerve injections – targets the nerve that runs along the front of your upper thigh and pelvis
