Pip

I have just been refused pip after the mandatory reconsideration notice,I haven’t enough points to be awarded it,I have severe osteoarthritis in one knee,and because of an accident a few years ago have difficulty lifting with my left arm,I have trouble walking and getting upstairs,I do work and people have to help me there to, a woman at work got the lowest amount after an appeal,with the same thing as me,and she isn’t as bad as me,,is it worth going further with it?
