i have very bad pain in the back of my neck on the left side. it goes up in to my head and causes me headaches.. i have seen a clinical therapist and he said my heads not on right he said more but i didnt understand all the words he used. :) anyway he makes me relax my neck and cracks it loads and it does feel better afterward but im just wondering if its dangerous to get it done too much????

i havnt had it done in a few weeks,, im gettin pretty bad neck pain now again and the headaches are back, how soon after getting it done has bad stuff happened to people.??? should i investigate further????
