We had heard such great things about the injections, we were so hopeful too! I hope you have better luck with your 4th, after 3 my husband rejected any further because he had no relief after the procedure. The only relief he got was because of the anesthesia during the procedure, which of course he doesn't remember. But I do, vividly. Those 3 times are the only times in the past 2 years that I heard him laughing like his old self. I wish I could bottle those moments, they were so great.
