Upcoming F2F review

Just received review pip claim. Only had 14 months took 6 months to sort as refused no point. Done reconsideration and award highest on both. Now another review, really worried as last face to face i was not accepted. Have to go though it all again. I sent in letters from hosiptal up to date. Think my big mistake was not saying no change, if any its worse. I have damged 7 discs in neck and 4 in back one is on my spinal cord so most days its hard to get around. I damaged my neck 25 year ago its never gonna get better unless i have op. But my heart cant take a op so i was declined.  All in all im not mobile a lot, but the pain, and pins and needles and numbness some days gets so depressing, and now this again. AS anyone elsr had review face to face
