Anyone have any encouragement to offer. I am 3 weeks after TLIF for L5/S1. Recovery going pretty well other than I have lost the ability to sit up straight for any length of time. I once I am in the sitting position, within minutes I get sciatica pains in my right leg. More than before the surgery. I can walk almost a mile and walk around the house well. As long as I recline I can ride in the car.
