HI there, just thought i'd share my good news
I was initially given lower rate care and zero points for mobility. I sent them a (strongly worded) letter advising that I thought they had made a mistake, pointing out that RA doesn't only affect my upper limbs (which they alluded too in their decision making) but my lower limbs as well. I have now received the lower rate mobility which I am delighted with. I knew I wasn't "entitled" to the higher rate, quite happy to accept that, but did feel they couldn't completely rule out my difficulties with walking and moving about due to RA yet accept I struggled with my hands etc.
For now the stress has been removed worrying about the DWP, ATOS etc.
DO hope those still fighting for their PIP get good news soon as well.
