Hey K. -
I can't speak for the hypnotherapy but I am a big believer in acupuncture and chiropractic therapies. It is amazing what one tiny little nerve can do to your entire body, or how one small vertebra can be the root cause of severe abdominal pain.
The best thing to do would be to find a very experienced acupuncturist through someone you know or through several recommendations. I would also, as a general rule, stay away from those located in day spas or other luxury facilities as they tend to be over priced and (in my opinion) just there for the "scene" and not for the holistic healing of the body.
One last word to the wise - should you pursue this, you are going to meet strange and "new-age-y" people. Don't freak out. My chiropractor is kind of a nut, but I love her! I just thought I'd mention it because some people go into offices relating it to a physician's office, but they get in there and are like, "Woah this is weird" ...just go in with your guard down and your mind open, and I promise you'll be glad you did. Acupuncture and chiropractic therapies and helped relieve (for me) - back pain, migraines, stomach trouble, severe abdominal pains, labor and delivery, mild arthritis, and most of all, stress!
Angie's List is a great website to find good details and opinions on businesses, doctors and other service providers in your area.
Best of luck!
