Oh I do feel for you, joolz. I was walking the dog today and actually thinking to myself that I don't enjoy walking the way that I used to, and it all goes back to having a bad knee several years ago. I'd twisted my knee but could still walk until one evening, on leaving a theatre in the middle of Nottingham, I couldn't put anyweight on that leg. The S.O. had to leave me propped up against a wall while he went to get the car which was parked quite a distance from the theatre. I couldn't walk properly for months afterwards and, even then, found that I panicked when I had to walk across an empty space. For someone in that frame of mind, ice is the arch enemy because, not only will it make us fall again but it is invisible, like our very fear of falling. In my case my fear now is of walking a distance from home and then not being able to get back. I do think that, perhaps, you should see a doctor as it seems to be affecting your life and you need help to get your confidence back.
