Well, told the doctor all about my issues with pain in my back, down left leg and into foot. Xrays showed that L4-5 still not fused by L3-4 solid. He told me 2 options: try injections or surgery. I went with the surgery.
He will fuse L5-S1 and look at L4-5 and possibly do that one over. I wonder if the L4-5 didn't fuse because of the stress from a bad L5-S1? Anyway, surgery is scheduled for August 4th. Hopefully this will get me back on my feet.
