PIp review and changes in circimstancesllo

Hello, I contacted PIP and informed them I would like a review of my health changes as things have deteriated considerably, since my award in March 2017. I was under the impression that they would just send a review form for this, however when I contacted them they informed me that they sent the PIP1 application, as my award runs out in 2021 and how it was up for renewal, is this correct??. I have several consultant letters outlining and diagnosing fibromyalgia and bulging discs in my spine and neck, also how I have has several lots of treatment and a negative spinal injection, do you think that I will require a face 2 face, or has it be known to be agreed by the decision maker

Hello, I would just like to thank benefits and work site for the useful information I gained, from Standard care I have just been awarded enhanced care and mobility without the need for interview, I sent a lot of consultants evidence in relation to all of my issues. I have been awarded this for only 3 years despite the conditions I have will only get worse due to age etc. I contacted them to ask why this was only for 3 years when I had standard care I had 4 years award and I was informed that this would be due to changes which could take place, Would I be able to ask for a MR for the timescale, without this changing the award , thanks

Thank you for this information much appreciated
regards
