it is definitely possible...but only if you work at it slowly but surely. I can't hop, skip, or jump...something about the impact doesn't agree with my body...but stairs aren't a problem except with the worst flares and with my walker (4 wheeled rollator) I can walk for hours usually just taking small breaks as needed. It took a good year to get to this point and it took a long time to get the endurance up. I can't do as much with just the cane...the walker takes a lot more weight off the bad leg and helps with the balance a lot. Added bonus that people tend to give me space in crowds and less worries of being bumped into. So keep working at it. With time you learn to recognize your own limits and can keep pushing yourself without overdoing it and causing a set back.
