If you pulled a muscle or slept weird that could be the reason. But if it is something to do with the bones, I think it would be beneficial to go. I have a lifelong neck and spine injury, I have to go to a specific chiropractor that specializes in head, jaw, neck, and spine. It costs more but it’s so worth it. It’s not traditional back chiropractic work, he doesn’t “crack” any bones. He actually just pushes my bones back in place/where they should be.
