Yes!, I find them to be useful, I have 2 injections twice a year as you can have them every 3 months if need be as well, fyi ...I go for 2 next month can't wait. Oh and you are awake and there is some pressure and a stinger/shock type feeling but that just means they hit the spot, all good and they talk you thru it all...If you are anxious like me ask and they will give you a cool cloth for your forehead and play some music...it's all worth it too IF they work for you, as some don't get any relief all depends on your body system etc.. I am lucky been having these for years everywhere heh.
