good morning,
yes, I have had one session of trigger point injections and didn't have any relief. For me, it was one of most painful procedures I've experienced. Doc wanted to inject lidocaine to lessen pain but I am allergic to it. That may be why it was so bad for me so I don't want to discourage too much. I couldn't make myself go back but he did say if they don't provide relief at first I could try 2 more sessions. Everyone is so different so it may work for you. I know with this condition almost any pain relief procedure is worth a try. Good luck , if you decide to do it I hope you'll let us know how worked for you?
