Hi Steve
I see your last post about this was two years ago - so you have been waiting a long time. You could report a change of circumstances and report how your condition has worsened. How soon it would be dealt with is impossible to guess in the current circumstances. However, if you got an increased award, it would be backdated to the point at which you informed them of the change of circumstances.
