Hello, I am new to this site, but I am not new to chronic back problems. I recently had L4/L5 fused in February 2012. I am little over 3 months post op and in a great deal of pain still. I have sciatica and muscle spasms as well. I had a MRI last week that show a disc herniation at L3/L4. I have followed all my restrictions. Has anyone else had this experience? Thanks for your help and advice.
