hi Emil
good luck with the acupuncture, the head and neck pain defiantly go together many years ago I put my neck out carrying 6 meter of 150 mm pipe, I had traction for a trapped nerve but was left with a tight muscle in my neck my doc tried drugs but that did not work so he, tried acupuncture and after 2 treatments it was fine I don,t know if it the same for you but but I cannot tell if it the neck pain causing the head pain or vicer verser my head ache develops into migraine type if I do to much of anything
