I have over past few years been able to work 12 hrs a week and claim standard pip only as did not qualify for mobility. I also get higher rate of lcwra . The pain in my back with spinal disease and osteoarthritis both knees is getting to much. I prescribe morphine so I find walking and especially going up and down stairs to much . I don't know if to inform pip about this or with everything going on would they care .My pip review been extended again. I welcome any advice. Thank you for your time.
