I received my letter today advising that I haven't been successful for PIP. I scored 6 points for daily living and 4 points for mobility . I got 0 points for cognitive function - possibly because I managed to spell world backwards and remembered 3 words ! This does not accurately reflect my cognitive function . I'm currently off work sick and I am receiving treatment at a CFS service . Is it worth asking for a reconsideration , then appeal ? I don't have any further evidence other than additional fit notes and the letter from CFS service outlining my symptoms . How long does the whole appeal process take ? Thanks in advance .
