AWARD REVIEW ?

Hi all, today i received an award review form in the post. It states that it must be back with them by april 18th 2018. Just asking if anybody else has had this especially as my pip award does not expire until 17th march 2019. I have recently got worse health-wise and had to get a support letter from both my doctor & my housing association so that the local council can register me and then i can bid for a new home (** sighs, its gonna be a long wait , i know**). The reason i will need to move is because i have suffered a few falls and i have decided i need to have a mobility scooter, which i will have to pay for because my pip awards at present are both standard rate. I just cannot risk any more falls, especially as i have already had 2 heart attacks (2012 & 2016) i was told by a few people not to contact the dwp and inform them of health worsening as they stop your money until the make their decision, how true i don't know.
Right now i don't know if receiving this award review is coincidental or not. Has anyone else had this or am i being singled out, what was the outcome?
Any information will be gratefully received from you and read with much interest.. Many thanks for reading this.... Happy weekend x shelli

Just to say I have also received my AR1 review form too , and mine was due the same day at yours and it has to be back on 17th April - it's like a recurring nightmare !!!
