Here's an interesting parallel: Dentists don't go to medical school either, but we use their services! That being said, I can totally understand your husband's position. My husband was the same way. However, we have a number of trusted family & friends who swear by their chiropracters and have had back, neck, knee, etc ailments that went away after visits to their chiropracters, whereas traditional medicine had no treatment for them. The issue with my husband is that he knew a guy in high school that was a total slacker--I mean, big time slacker--poor grades, poor attitude, you name it, and the slacking continued into adulthood. After floating around for a while, he settled on chiropractic school. Needless to say, that didn't elevate chiropracters in my husband's eyes!
But having so many of our family & friends benefit noticeably is turning the tide.
However, do NOT use Chiro One clinics. They're a joke and a rip-off. They will take your x-rays, tell you how your body is severely messed up, and tell you that you need to visit them at least 3X per week for 13 weeks, custom shoe orthotics, and physical therapy...and you have to pay for it all IN ADVANCE!! Any reputable chiropracter will treat your visits like a normal doctor--you pay as you go.
Plus, many big insurance companies cover chiropractic services. Believe me, with the insurance industry the way it is, if it wasn't recognized as a viable treatment, it wouldn't be covered on any insurance! Thankfully, our insurance does cover treatments, so once I do find a chiropracter I feel comfortable with, I'll start some treatments.
Chiropracters aren't doctors. But having someone who knows the anatomy of a back, who knows how to properly release tight muscles and help work the bones where they are supposed to be seems like something that could prove useful to those of us with pain.
