You know, I never would have tried it, but I was miserable, period. I would have let a china-man make a pincushion of me so I figured why not... worked.
Also, this may help you and it may not. But I just this week have had a bit of pain in my back for the first time in a long time... real low along the belt line above the rear pocket from the spin e out to the hip.
In this case, it turns out it is not my back actually at all. Sounds stupid I know, but it is actually referred pain from a trigger points in my leg.
If you will feel firmly you can find them along the outer halves of the backs of the legs for example. In my case I have 2 pretty ticked off. One just above the back of the knee with surrounding tissue swelled up about the size of a marble. Then another about a hand width above that.
The funny part about the referred pain is that you hurt in one place but feel no pain at all at the source until you actually touch it and as you start to work on it the referred pain just vanishes.
I have recently started back running and apparently did not stretch the one leg well enough after the last run or something.
