I can't really recall when back pain became a real issue for me but I have a feeling it was at a kettlebells class around six years ago. Something that started off as an irritating niggle in my lower back has stayed with me and it's now something I have to actively and regularly remedy with stretching and repeat visits to the chiropractor. Part of me wondered initially if this was just part and parcel of getting older and more aches and pains presenting themselves but the day my back locked and I couldn't move was a real indication that something more serious was wrong.
