I had friends that went to chiropractors for years. I worked for the DOJ in Corrections. An inmate punched me in the jaw. I was alright, but I couldn't bite down on my right side. I had my jaw x rayed and was told there was no fracture and in time, it should be alright. After about 4 weeks, I was referred to an oral surgeon. He looked at it and found nothing wrong. He stated if it wasn't back to normal in another 4-6 weeks, I would just have to live with it. I got used to chewing food on the left side of my mouth.
I had some issues with my hip and had some discomfort while running. A friend convinced me to see a chiropractor about my hip. When I went in, I completely forgot about my jaw. As the chiropractor was doing his routine, he had me touch my jaw while he moved my leg and hip. He then asked me if I had problems with my jaw. I was shocked. I told him I certainly did have issues. He determined that my jaw was slightly dislocated. He actually put it back into place and fixed what the oral surgeon could not identify. He also fixed my hip issue.
That is why I am a true believer.
