Oh, and chiropractic is definitely NOT hokey. It just shows how out-of-touch your friends are (sorry - no offense). People who get regular spinal adjustments are healthier overall than people who don't. For instance, I haven't had a cold in years!! And, I've only had the flu one time in ... well, let me think... how long has it been? Gosh, I think it's been about 14-15 years, and I've only had the flu once. Wow! I didn't realize that until just now.
When a vertebra in your spinal column misaligns, it cuts off proper circulation and energy flow to the part of the body that connects to the central nervous system where that vertabra is. Think of it like the wires that run along the telephone poles on the side of the road. As long as those lines aren't obstructed by anything, energy flows to the houses in that area and people's lights and phones work. But, let's say a transformer blows on one of those poles, cutting off the flow of energy. Everyone's lights and phones in that area go out. Same with your spinal cord. Every vertebra houses a connection of nerves to the central nervous system, by way of the spinal column, which leads up to the brain. The brain sends signals out through the central nervous system, and if one of the housing units (vertebra) is pinching off the nerves it houses, the signals from the brain can't get through, and vice versa. This could be the reason why you experience tingling or other weird sensations in certain parts of your body. It could also be the cause of headaches, hunger, bowel and digestive problems, and a whole range of other problems.
I've known people who've allowed a misaligned spinal cord to go for so long that they lost the use of one of their feet. The nerves actually died as a result of them not getting their spinal cord adjusted, so they can't move their foot anymore. I could feel that happening to me during a time when I wasn't getting adjustments, and I immediately started seeing a chiropractor again.
Sometimes when I get an adjustment, I feel a surge of energy rush through my body. It's like everything was closed off, and when he puts the bones back in place, it's like someone just opened the floodgates.
