I am 7 weeks post op from a L4L5 discectomy and still find I can not sit in a car longer than five minutes. This is very limiting to say the least! I can sit at home for 15 to 20 min pretty comfortably. I do lots of stretches and I walk 20 min twice a day. I have tried all kinds of cushions,wedges,lumbar rolls...you name it. I couldn’t sit at all for eight months before my surgery. Does anyone have any experience with this problem?
