I've been having trouble walking because my right leg feels as if it's going to break off, right at the beginning of it (where it starts at my pelvic region). Can anyone tell me what might be happening? If I set out to walk, it completely stops me in my tracks. Does it happen when you overdo it? I did walk a long way on my lunchbreak yesterday. And I walked fast, as I was hurrying to get back to work on time. I really think that I need a mobility aid, but something lighweight and not cumbersome, like a wheelchair or scooter. Any ideas? A rollator with a seat and a basket, perhaps?
