Hi I am waiting for my surgery to get scheduled.

Hi I am waiting for my surgery to get scheduled. Achilles bone spur removal etc.. and a tear in my retromalleolar peroneal brevis. (Sp?) I don't do very well on crutches. Was just on them 3 weeks. Am wondering is a walker easier to use and less painful? Also how difficult are knee scooters to get in n out of cars? Anyone have similar surgeries? How long should I expect to be non weight bearing? Thank you
