I can't find the post that we were talking about back pain. I was commenting how bad mine was I was going to get an injection. I did on Friday in my sacroiliac on the left side and WOW no more pain. I dropped my car key in the parking lot yesterday (Saturday) and wasn't sure how I was going to pick it up because the previous pain was that bad. I bent over to grab my key and stood right up no problem and no pain! It was amazing. I feel good again.
