Hello, all. I'm new to the board here. I've been reading through some of the entries and they are quite information and impressive. I just had a spinal fusion of L4-5 and L5-S1 about 4-ish weeks ago. Until today, I've had a debilitating pain shooting down the back of my left leg. It's not nerve pain (that is all gone, thank goodness). It's more of a feeling of a very badly pulled muscle that goes from my glutes to my hamstrings. Has anyone ever experienced anything like this? Also, I had trouble urinating for a week of so after surgery...anybody experience this unpleasantry?
