I would highly suggest a walker on wheels....they're called "rollators". I have one simply to prevent falling. However it's extra nice as I can sit anytime my back/leg starts hurting or I need a breather. If you decide on one, be sure the storage area under the seat is made of vinyl so it will fold up easily. Other considerations are its weight capacity and its width . The 1st one I got was 1" too wide for the doorways in the hse. Any medical supply place has them as well as Walmart, Walgreens and other places.
