I met a lady whilst wobbling about on uneven ground. She was similarly wobbling. It led to a conversation about the reasons for our wobbles. When I mentioned the MS, she responded by saying "oh poor you! I only have osteoarthritis". I would have thought the same about her if she'd have told me first about the osteoarthritis..that's actual proper pain...poor her!
just goes to show it's all about the view from where you stand (or wobble!)
