We have lots of members who have received PIP with these conditions but it is important that you understand that it is not your conditions that will be assessed but the limitations that result from them.
See our PIP Claim guide for the criteria that you will need to meet
www.benefitsandwork.co.uk/help-for-claimants/pip I would chase the referral if nothing else it may help you with conditions.
I can't see any value in putting the Consultant down as a medical contact if they have not seen you for two years or more.
