Interesting. I am having terrible upper back, neck and shoulder pain. Been stretching and icing and heat, but nothing helps. Thought about a chiropractor , but haven't tried that yet. Perhaps it is, indeed, related to the meridians. I've had acupuncture before, but not for years. My shoulder pain however is a long term problem. Probably rotator cuff from an injury many, many years ago. That said, it us worse than ever since surgery. Perhaps I'll try acupuncture. Not too happy with my current GP and trying to find a new doctor in an area where health care is pretty abysmal. I'm in a rural, small community in northern California.
