Getting those shots is scary with how bad infections can be due to pharmaceutical overuse/misuse breeding super bacteria in hospitals and clinics. That's a one way street too, loaded with a bunch of other bad things from long term use.
Chronic pain sucks. It'd be great if you could find another type of treatment, or at least something to postpone the joint jabs.
On a funny medical note, I came across an odd documetary today, The Dickumentary. It stretches across several chapters, but one guy with a perfectly functioning member decided to risk going through enlargement surgery. He did end up with a larger penis, because it got infected. The thing looked like a large pink grubworm and he commented on how he thought it was a good looking penis before surgery. Doh!
Maybe that wasn't funny to him, but i laughed.
