Anyone Tried Prolotherapy Injections for Joint Pain?

Hello everyone. I've been looking into prolotherapy injections as a potential treatment for joint pain and ligament issues. From what I understand, it’s supposed to stimulate healing by injecting an irritant solution into the affected area. I’m curious if anyone here has tried it—what was your experience like? Did you notice lasting results, or was it more of a temporary fix? Also, how many sessions did you need before you felt improvement with prolotherapy injections in Portland​? Any insight into pain levels during/after the procedure would also be appreciated. Looking forward to hearing about real experiences before deciding whether to try it! thanks in advance for any help
