I am due for a bb assessment. This is my first renewal. My first application was accepted at once. I suffer from osteoporosis and peripheral artery disease which three yrs ago was a listed reason for a bb. But not now and this time I had to sent resent documents. Well I was diagnosed 16 yrs ago with pad and 26 yrs with osteoporosis. I have walking difficulties due to severe pain and leg cramps which stops on rest so I have to walk slow and stop and start very often. Which can take ages to get to my destination. They are not happy with my latest doctors summary which lists these conditions plus osteoarthritis in my knee. So I can walk normal for about 5 to 10 minutes sooner if walking up a-slight slope and then the pain is extremely painful. How can I demonstrate if I have to walk up and down the room where they test you. I’ll be so annoyed if they refuse me as it’s difficult to prove pain with no limping
