Know the points, descriptors and criteria for a PIP award
One of the hardest things to do when making a claim is to adequately describe how your condition affects your daily life and or mobility
Just because you have a condition and diagnosis does not entitle you to a PIP award. PIP is awarded for the impact that your condition has on the things you can do.
Understanding how the points system and descriptors work is the key
Take each descriptor one at a time and explain, with examples how you are affected.
It can be very difficult to put into words because most of us take our limitations for granted and we have coping mechanisms in place to make life work for us the best way we can.
The assessors needs to understand your difficulties, two people with the same medical condition are not necessarily affected in the same way. So you need to paint a picture of your life in no uncertain terms. If you have familly or friends that know you well, they can often help with some of the things that you take for granted or don't feel are important.
You cannot rely on medical diagnosis or lists of medication and expect to be given an award.
The better the assessor understands how you are affected, the more likely you are to be given an accurate assessment. Don't expect the assessor to take your word for it, or understand that because you have such and such a pain you cannot do things.
The assessor can only report on your functionality on the day, they don't have a crystal ball
Be all you can be, make every day count. Namaste
