Hi Jeff,
If you are feeling pain, i.e. pins & needles, the nerve is inflammed indicating something is wrong. The worst thing to do is to carry on through the pain. I would get a professional opinion. But as far as surfing, if it hurts, then I would lay off until the pain is no longer there. Greeney offered some great tips. SUP could provide relief or a different type of board (bodysurf, matt, etc).
For land based training, I would try prone decompression by Eric Goodman of Foundation Training:
During you daily routine, you want to be mindful for possible triggers. With neck posture you want ears over your shoulders with your chin in. Imagine a string from the top of your head pulling your head up. Any daily routine where you chin pulls away from will put strain on your nerve (i.e. computer, phone, etc). Mountain bikie riding is a trigger for me, whereas beach cruiser is ok.
