Hi MM
Welcome to the Board & so sorry to hear about all your back problems. Wow

, you do have quite a few problems.
Anyway, what kind of injections are you going to be having next week? There are several different types.
As far as if they work or not is really whether or not your body responds to it. For some folks this procedure works well & for other's it does nothing for them. It's kinda like drugs, you have to experiement with several before you find the one that works best for you.
For you, I hope they work, it's such a pain to have to experiment. Good Luck Cat
