I have near constant neck pain and have done every route I can think to mitigate,manage,cure or deal with it. The strangest part is it switched sides randomly. I've tracked/logged it multiple times and can make no sense of why it switches. I think I need to track more things I'm doing to see what's related to it... neck surgery, stim, acupuncture, multiple types of therapies, heart, cold, massage, etc.. all give negligible results.
