The criteria for PIP is fundamentally different from DLA, for example; the reasons you have a DLA HRC award has no equivalent in PIP, so you cannot rely on the information you have previously submitted for DLA will help you to a PIP award.
You can request a copy of your medical records from your GP practice, this should any letters that have been sent by the Consultants that you see to your GP, this way you will know what is included but more importantly, can integrate it into your answer on the PIP2.
Please see our PIP Claim guide for assistance with completing the form.
