DM has had arthritis for many years, but in the last few months she's finding it harder and harder to walk far. She can still walk - but she's increasingly slow and unsteady, and it's now starting to affect her decisions (eg she didn't want to come to an event because the nearest place to park is maybe 300 yards away, and she'd struggle to walk there and back). I looked at the guidelines for blue badges, as I thought that might help, and the majority of the things on the list don't apply to her, but one of them just says something like 'if you find walking very difficult due to pain'. I've no idea what the definition of 'very difficult' would be, and whether there would be any point in her applying.
(NB she also has cognitive decline and anxiety, which doesn't help matters. She doesn't drive herself any more, so it would be a badge for my dad's car.)
Does anyone have experience?
