Yes, I had both SI Joints fused a few months ago and have been in worse pain since. Also had a Lumbar Nerve Block which worked. No or little pain for 1 year. Needs to be done again. Doctor is now talking about a cluneal nerve block bilateral. It's in the same basic area as pelvis and SI Joints. Not looking forward to yet another procedure. I'm beginning to feel like a pincushion.
