Can you explain how a nerve block procedure work inside of your body? i have had a couple of these for my neuropathy condition.

Blocks messages: All sensation and actions we do are sent as messages to our brain centers. When sensation messages are excessive, we register this as pain. Injections of nerve calming or numbing agents into nerves reduce the excessive messages and modify the pain perception. If this works but constantly recurs, the nerves can be permantly suppressed by toxic injections or surgery to cut the nerves.

Nerve blocks: Work by blocking the ion channels in the nerve, preventing the transmission of a message along the nerve. With local anesthetic, this effect is temporary. Other agents can permanently stop nerve transmission.
