Turned down for PIP - have osteoarthritis

I have osteoarithritis in most of my body inc feet knee's hips hands lower back it can be painful most the time but dwp won't even support me even with pip

hi there yes i was turned down for pip as i can still walk but not without pain  i only got awarded a couple of things and that was nothing for mobility just more to hands
i now been told i have arithitis in my feet and more than possibly hands as well .

but walking can be painful now more than it was on constant pain killers  etc and have overactive bladder  an mild depression
