Just had my C&P exam last Monday. Worried about the back exam that was conducted (DAV added it to my paperwork with other issues I was having with my knee). I have had a 40% rating for my back for 18 years. My concern is that they will recommend a reduction even though my symptoms have increased. The moving side to side I can do, cannot bend very far forward or backward. I was very straight forward during the exam, voicing what my limitations were. But I was reading on several other websites to where the VA goes by the bending and movement performed during the C&P for evaluating the back. I do remember my first exam I had a flare-up to where I could not bend anyway at all. That is where the initial 40% came from. Should I be concerned?
