I was thinking of starting a thread on this myself as I have had a very positive (probably life-changing) experience with a chiropractor
I have suffered from back pain most of my adult life and routinely saw doctors and physios through my Army career. Two years ago, I had an industrial accident in which a heavy weight landed on top of my head. I was saved by a site helmet and there was no major damage found. A very expensive private doctor in Miami told me he couldn't do anything for me.
Since then, my back has steadily deteriorated; constant pain in the lumbar area and neck pain, particularly when looking over my shoulder. I struggled with simple tasks like putting my socks on and could hardly walk when I got up. I was also suffering from constipation and low energy levels, was getting depressed and was putting on weight because I couldn't exercise.
Back in May, I met a chiropractor at the local autumn show. Along with most Aussie chiropractors, he was offering a free spinal examination and X rays during May, so I went along. I was frankly horrified when he showed me how my spine had degenerated and how out of alignment my pelvis was, neither of which had been picked up on by doctors.
I signed up for a course of treatment over 6 weeks, 3 times a week at first then dropping down to once a week by the end. The results are frankly amazing. Treatment consists of spinal adjustment using a spring loaded probe thing which stimulates the nerve endings; he does no manipulation. The body does the rest. No way is this a placebo effect; I've seen the evidence in my X-rays over an 8 week period.
I had an assessment this morning; my pelvis is now properly aligned, neck movement is normal, spine alignment much improved and strength and mobility are returning. I'm not pain free yet, but I ran 50km last week and did 3 gym sessions, something that was simply a dream 3 months ago. I can't remember having energy levels like I have now and my guts are working normally again. I've also lost 8kg since starting.
I have always been cynical about alternative treatments, coming from a family of medical professionals. Not any more; in 30 years, the medical profession never got my back right. Three months of chiropractor and I am better than I have been since I was in my twenties. I can safely say that regular chiropractic care is now a fixed part of my life.
