I have also had lidocaine and nerve blocks. Don't think I ever really got relief. I also had epidurals which also did not help. I have tried acupuncture and many different meds. I have to saythe only thing that helps me is percocet which is short lasting and addictive. also, you develope a tolerance and you end up needing more. I have also tried narcotic patches.

Best of luck. It is a very frustrating thing to deal with. Linda
