Sorry you're laid up for a while.
I had the same surgery but one level higher, about 18 months ago. 100% cure. But, and this is really important, you MUST follow the doc's instructions. My doc said no lifting more than 2 pounds (or was it 3 pounds?) for a couple of weeks. No using the vacuum for 3 months. No lying on soft surfaces like a puffy couch.
I was surprised how physically unable I was for at least a month. Just walking around the condo parking lot was painful and exhausting. At 2 months I was feeling ready to be a lot more active, but the doc and physical therapist were putting restrictions on me.
At 3 months I went back to work but didn't want to. I had to for financial reasons. Walking was fine but sitting was still painful. Lifting overhead was tricky, so I learned to travel super light.
The physical therapist was a really attractive and very interesting woman. Too bad it would have crossed all kinds of ethical lines to ask her out.
The modern back surgeries are really good compared to even just a few years ago. Your chances of being pain free are excellent. But be sure to follow instructions and be a good patient for the next 4 months!
