I personally a few people with terrific responses to prolo.

My sinus doc had it for his back, and it didn't do much; he had it for his neck, and he is finally pain free in that area.

A second had it for a painful knee that surgery was recommended on--he's diabetic and overweight--and he is pain-free. The third I can think of, offhand, had it after spinal fusion was recommended for disabling back pain due to herniated discs, and she is totally pain-free.

I do think that this, like other procedures, needs to be done on the right patient by the right doctor.
