Lets you feel things: The nerve root has 2 "ganglions". The dorsal root is on the posterior side of the nerve (closer to your back) and carries the fibers that allow you to feel things in your extremities (for example: pain, temperature, vibration). The information is transmitted to your brain so you understand what type of sensation is being encountered by the extremity.

It is the region : Where the neurons are located for the spinal nerves that send signals to the brain and the ganglion is very sensitive to pressure and ph changes or acidity.

Pain, burning: The dorsal root ganglion is a very sensitive part of the nerve origin and may be damaged. It results in severe pain, burning, tingling, numbness, and weird sensations such as a feeling of bugs crawling upon the extremities (called paresthesias).
