Just had L4-S1 fused on December 15th. I went through multiple pt attempts, multiple epidural steroid injections, had the L4-L5 disc trimmed, and after all of that ended up getting it fused as nothing else worked. So far I'm doing well. It's not the most comfortable surgery, but it was my only option at pain relief. I'm 35 and didn't really want this, but I couldn't function anymore.
I was in a bad car accident in July of '15 which caused my issues.
