connections?

I've been seeing a chiropractor recently for my back and noticed that the first couple of treatments left me feeling very vulnerable emotionally. Somehow the manipulation of my body had a impact on my mind and spirit. Maybe it's just a coincidence, although my chiropractor said that she has had people burst into tears at times when she has been treating them. And a friend who has had acupuncture for a sinus condition testified to a similar experience. Makes me wonder  how many of our physical aches and pains have their roots in emotional dis-ease and vice versa.
