9 days post op TLIF L2-L3 and second day of outside walking. Walked 1 block Thursday 2x that day and was sore. Skipped yesterday and stayed on ice all day. This morning made it 2 blocks which is probably about 1/2 mile. Will see how I feel this afternoon and if ok will attempt the same walk. I can tell you from experience that this level is much easier to recoup from than when I had L4-S1 done. Those 2 lower levels don't even compare in my experience. I guess the muscles and the new hardware all have to get use to each other is why the walking really helps. This recovery is showing to be much like the L3-L4 fusion. My walking pace is very very slow let me mind you and I get back on the ice when I'm done. I only get up and sit for no more than a hour at a time as my brace really irritates my incision area right now which is probably 7" long or so but should get better. The bed and ice have really worked best for me the first few weeks. One other helpful tip is to avoid inclines when walking as they will make you strain. A very gradual incline in a street is not bad if you take small steps or slow your pace.
