I list the low-hanging fruit first:

Look up nerve flossing exercises on YouTube. Routinely doing these had the largest impact for me. You'll feel the ones that work on whatever nerve is inflamed.

Try to improve your posture. My general mantra is "lift your head as much as possible. Pull your shoulders back". It gets easier eventually. If your head lies forward from the spine you have a hunch. You may notice a small lump of muscle behind your neck. That's bad. There are exercises to try and strengthen the opposite muscles.

If you sleep on your arms try to stop as well. I recommend sleeping on your back. Fluffy couches and back rests sacrifice posture. Don't use a laptop in bed.

Sleep, eat nutrient-dense foods, and run or swim. Avoid alcohol. If you do pushups or bench press, make sure to exercise your upper back equally to avoid imbalance.
