I gave 'one of nzs best' chiro's a fair crack to try and get rid of some neck pain of mine.. after 6 months of 'treatments' it wasn't worth the money nor would I personally recommend chiros as an effective source of treatment.
though my issues sound minor in comparison to yours I've found the best treatment for me was doing exercises that strengthen the areas of concern
One of the other interesting effects of muscle strengthening is that I find my balance is a whole heap better too which is a good bonus when you're aging
networkn: I'd highly recommend a musculoskeletal specialist.
im going to look into this too, could you recommend anyone?
