Anyone had hylauronic acid shots in joints?

My orthopedist and I have decided that HA shots are going to be the way to go for me since I really, REALLY do not want knee replacement. I know this therapy for horses works WONDERS but you can’t ask a horse if it hurts. Well, you COULD but…

Anyway. Has anyone had 'em and are they more painful than cortisone shots? You’d think after a medium sized tattoo and several piercings that pain wouldn’t be a big deal but it’s nice to know in advance.

Thanks! I love this place.
