I've decided its about time to get a walker. I don't need one for stability as I rarely have vertigo issues anymore, and fall risk is very low for me. But I so often get caught having to go to the pharmacy or somewhere and get caught standing in line for a few minutes. Standing kills me very quickly, so I need one I can sit on comfortably. Below is what I am thinking of, but I would like to hear other people's opinions on what has and has not worked for them. Will I wind up fatiguing my arm muscles too much walking with one? How does your favorite one function? Foldability? How well do they actually help us ME/CFSers? Life saver? Moderately helps? Have you ever used one in an airport instead of hiring a wheel chair? Or for that matter, ANY air travel stories with a walker would be nice. (I will need to fly here soon...) Thanks in advance!
