I had a really bad motorcycle accident a few years ago. After that, I started getting really bad headaches and also my RSI/CPS started getting much much worse.
When it got to the point when I really couldn't even write for more than about 10 mins because the RSI had gotten so bad, my GP referred me to a chiropractor.
At first it was just really scary – the chiropractor cracked all manner of things I hadn't even realised should be able to move! He figured that most of my problems were because my back had healed incompletely after my bike accident. But I immediately had some relief from the pain and started to think perhaps it would help. He also used ultrasound and accupuncture on my worst affected muscles and that really helped to. After a course of treatment I was sorted!
Up until then I'd only regularly been able to crack my fingers, wrists, ankles, knees and hips. The chiropractic treatment must have helped with some stuff, because my back and neck and chest and arms are now able to crack -- whether it's good for me or not It's all much looser, my RSI is under control again and the tension headaches are virtually gone
I'm a big advocate of chiropractic now, as you might have noticed
