Second assessment for PIP

Hi
I am new to this so please excuse me if my question has been asked by someone else.
I live in Northern Ireland and was on DLA which was for an indefinite period, towards the end of last year I had to apply for pip and had my face to face with capita in my home in December, today I have had a call from capita to say that I have to have another assessment which again will take place in my home, when I asked why I was told that the TWO have asked for further information to allow them to make a decision on my claim. The lady who called me said this does happen sometimes if they need more information, I am sick with worry I was already suffering with even more anxiety than usual due to going through this process. Can anyone tell me if this does happen and what I can do to give further information I felt sure we covered everything in my assessment.

Sorry for the long winded message.

Thanks,

Hi Gordon

Thanks for your reply unfortunately was had forgotten until today that I had already asked you about my second assessment, one thing I forgot to ask originally am I allowed to ask the DWP before my second assessment next Monday what the additional information that they require is, I thought the original assessor was very through so I have no idea what extra i can tell them that I haven't to do already.

Thank you Gordon. I phoned the DWP about 2 weeks ago to ask if they could tell me how long it would likely be before I heard about my claim and was told that the report had just arrived then 2 days later I had a call from Capita to say that they had to come out to see me again as the DWP had requested further information which is why I was I have been so anxious about it due to as I have said I thought I had answered everything the best I could. I know they don't take into consideration that I had been on DLA which was on an indefinite basis so going through this all over again is honestly adding to my health problems. I know I'm not the only one in this position but it makes you feel as though you are. I appreciate the information you give within the forum.
