Hi tector,
I think it would be preferable not to use redacted documents if possible - the DWP are bound to suspect that you are trying to hide information not in your favour. For your social anxiety I suggest that you should also find something more recent that says how you are now, or that your condition has not improved/has worsened or whatever is the case*.
The neuropathic pain is likely to be less variable but you will have to show that you have not 'adapted' to your condition and/or that it is not adequately relieved by treatment.
*If possible but I know that many people are 'parked' by the NHS as there is nothing more than can be offered. You cannot submit what you do not have.
Nothing on this board constitutes legal advice - always consult a professional about specific problems
