PRP vs Prolotherapy for lumbar/SI - pros/cons?

16 months of a limp is nothing. I vaguely remember when I measured chronic pain time in months, not years.

I had PRP done on the tendons in my ankle, in conjunction with arthroscopic debridement. My doc isn’t a huge fan of it. I’ve tried everything else. As I told him, at this point I’m open to snake oil & Hail Mary passes. If I just get a placebo effect from something, frankly that’s FINE. A positive effect is a positive effect.

I didn’t notice any pain from the injection, but I was on post-op narcotics.
