I tried acupuncture a few times so far. I find you do feel a bit different. I'm doing chiro, physio and acupuncture at the same time, but when I added chiro and acupuncture in I found my headaches are still there, but less frequent and neck pain is quite a bit better from both.

One thing to remember here, is that if you can afford to try it, do it! I'm in Canada, and I'm fortunate enough to have at least partial benefits as well as insurance from my sport where I got hurt. I've tried almost everything in the book! Everyone feels different from acupuncture. Mine happened to be a naturopath as well so he gave me some hints on dietary stuff to consider as well as vitamin remedies. If you can find an acupuncturist who is also a naturopath, I'd recommend it!

Hope you find some relief!
