If you go to the Health Board headers and type Prolotherapy into the serach option, you can find everyone here that has had it done and who had shared their experiences on the boards.
I had it done one year ago. I didn't have enough sessions and was re-injured. Insurance does not cover it, so be prepared to pay alot. It is around $500 per session and it takes a minimum of six treatments to obtain results.
I went into it as a skeptic but came away with tighter ligaments. If I had not re-injured myself, I think that I would be painfree right now. The only other way to tighten up the ligaments is surgery. They are not like muscle, they don't tighten on their own. It is like women's breasts, which are also composes of ligaments, once they sag, they stay that way. Think of the ligaments in your back as sagging. That, in turn, makes for slop in the movement of your back and SI joint, as well as the hips. This caused me to have arthritis in my spine.
There is another person on the boards, Heidi, who had it done. She is a proponet of Prolo.
Research it and then find a spine doctor who you feel comfortable with. I would not have it done by anyone less than a spine specialist.
We had one guy in town who runs a pain clinic, spine specialist who does Prolo, but on closer examination of his practice, which changes names about every six months, he had his license to do surgery pulled and is trying to make it by doing Prolo. I would not use someone like this. So, do your homework before you have it done. They put a lot of shots in your back so pick someone that knows what they are doing.
