I’m on the waiting list for an urgent knee replacement and I’m finding it more and more difficult to walk any distance, even using a walking stick. It’s not only the pain but the effort of walking that’s getting more and more difficult. I feel out of breath and that I can’t walk any further without sitting down. I’ve also got spinal stenosis. It’s very depressing and I’m not able to get out and exercise. Is this normal with OA and will it only get worse the longer I wait for the operation? I wondered if anyone had any advice please. Thank you.
