chiropractors are the bomb.
my dad was in the same boat, had really bad back pain couldn't hardly move at times not a good position to be in for a mechanic!
and then my mum was working with someone at the time that was going to a chiro and basically swore black and blue that all her aches and pains were fixed so my mum booked my dad in and after his third visit i think, he was back to work moving well and everything. after that i made my mum get me an appointment as well. i really can't praise them high enough. if you have access to one GO FOR IT
