Oh my other advice - see if you can line up a temporary handicapped sticker for your car to save walking when you don't need to. Also, if you think there is any chance that a walking frame could help, then use it. PPl will pay attention to how bad it REALLY is if there is an external prop. Otherwise you might find they are clueless even after you've explained what's wrong a dozen times. (Ppl think it's 'ordinary' to have pain late in pg and just don't get that your condition is far worse than that). Good luck, let us know how you get on.
