Yes! I assume you want personal stories more than info about the procedure (that stuff is on official websites). For me, I had terrible pain from 12 years old to 17. I got my first treatment on my 17th birthday. I wasn't sure I could go to college, because my back and joint pain was so bad we didn't think I'd be able to get around campus (especially not carrying books). I have hyper mobility syndrome. After about 3 treatments of prolo in my back, it started getting less painful. Then, we started adding in joints to the treatment (a knee here, a wrist there) and in less than a year I was 70% better. By the time we were done I was 80%-90%.
I haven't had a treatment in about 4 years now. I rock climb, train Brazilian Jiu Jitsu, do yoga, run, and just spent the summer out west building trails in national parks (swinging picks and shovels all day). It's really awesome. I'm pretty much a normal person now. I'm a bit more injury prone than a normal 23 year old, but if I'm careful I don't run into problems.
I kept a blog about it when I first started getting treatments. There are some graphic pictures of the needles going in, so if you're squeamish maybe skip that post. http://prolotherapyadventures.blogspot.com/
