I agree 100% with
@CasualSpinner . I suffered for about 12 years after a car accident (which probably weakened something) and soon after a sneeze as I tried to do my shoelaces I kid you not. I tried painkillers, chiropractic, osteopathy, acupuncture, whinging, feng shui, heat pads, cool pads the works. Nothing helped. And probably just made me more suspicious of the snake oil treatments. They wouldn't do a back operation because I was "too young".
Until I came across a physio who listened, looked and thought about it for a couple of weeks. He came up with a plan to improve my core strength, worked abs, kegels, obliques on one of those giant bouncy balls. After about 3 weeks (well 1 visit per week and home exercise, the pain was 75% gone. After a month no more pain. That was about 15 years ago. I had a couple of instances where it returned where I'd had an extended time in the office moving papers from one side to the other with sh*t posture. But back on the bouncy ball, same exercises, and it lasted for a day each time.
Made a huge difference to my life. No longer grumpy. Well......less grumpy.
