Hi there Mamasan2007,
I suffer from sacroiliac dysfunction due to a workplace injury and prolotherapy was one of the conservative treatments I've had. When my specialist first brought it up I had to admit, I was skeptical. Since I'm a student of Kinesiology/Health Science, I went and did my own research. From the research I found, some subjects found pain relief...others did not. Even though I didn't like the sound of getting approx 10 injections in my lower back, I went for it. Since there is no absolute concrete evidence that prolotherapy works 100% of the time, my workers comp insurance and my parents insurance didn't even cover the expense.
With prolotherapy, they inject an irritant (in my case cornsyrup), which causes massive inflammation in the injection sites. This signals the body to repair the "damaged" tissue (and in my case, hopefully rebuild elastic tissue in my sacroiliac ligaments).
Let me tell you, in that case it worked. I was so inflammed, I could barely walk. Going through the three consecutive treatments, I could barely move and was incapacitated for a month.
Long story short...prolo didn't elevate any of my pain, and six months later my hips are still crooked, my ligaments are still lax, and I'm still in pain.
I suggest before having prolotherapy do some research...there are some excellent med journal databases with peer reviewed studies. I did that, but I was still naive, because my specialist tried to sell it to me as a "cure all." Later on he admitted to me that most of his patients get anywhere from 6 months to a couple years of pain relief before they're back in getting prolo again.
In sum, prolo is not a "cure all" and it may or may not provide any pain relief.
I wish you best of luck in your pain management, and trust me when I say, I know its not easy!
