I hope you never have to experience nerve pain! It happened to me in 2017 and it was excruciating! I told Peter, "If I had to live like this I would not want to live" that is how bad it was. After getting x-rays and an MRI they discovered that a small shard of bone from one of my cervical vertebra had sheared off and was pressing on a nerve. The resulting pain was felt in my left arm. It was a pain SO DEEP, so all consuming I could not lay flat, could not sleep, could not think - not to mention being unable to do any of my usual things like gardening, working in the studio... I was not myself at all. My little story explains it better than this paragraph can. I am happy to say that I am completely back to myself now! It took me a while, nerves don't like to be messed with.
