I bought a Rollator and it helps so much. I have been able to do grocery shopping easier and even travel and go to concerts!
I am older, 34, but I definitely still get looked at for being “too young” and not “look sick” enough to use one. My boyfriend is great and always reminds me how much it helps me and that he and I can do so much more together because of my Rollator.
Take care of your body and if that means using a walking stick, go for it! It keeps you more mobile and you exercises more with it and it probably improves your posture too. You benefit from using it. Don’t let the looks discourage you from feeling better.
