Hi there, hope you are ok.
I imagine you are not looking forward to it at all.
I know that I have read that when DWP doctors visit other people, they put their tablets, equipment and other vital stuff near them - this will show the doctor that you struggle with walking so you need to be near things as possible.
I know it sounds daft bu the dwp doc will look at everyone. For example, I know that some people have said that dwp docs will look at somebodies walking stick to see if the ruber part of the stick looks worn...stupid I know, but they do look at everything.....
Luckily, I have never had one yet...but I would not enjoy the experience, as we all know that fibro and related conditions are hidden disabilities, so it can be hard for anyone to know who much someone is suffering.
Hope it all goes well for you anywhere. Contact citizens advice bureu or your local welfare benefit centre for more information....If you can, get an advocate when the doctor comes, so if you feel you cannot cope then you can have someone supporting you...always help for you to have someone there, then it looks better on your part.
