I have had PIP for my heart and arthritus conditions then told them about how my condition had worsened with fibromyalgia just attended the new assesment . There is a site called (Email address can only be seen by the question and answer creators) which I signed up for which really help with what to say when you go. Yes it is recognized now as a long term illness.

Personally unless your FM causes significant changes to your previous assessment I would leave well alone. It is classed as a disability in the UK.

ADP is for people living in Scotland, if you're already claiming PIP in Scotland then you'll be transferred over. PIP is about how your health conditions affect your ability to carry out various activities of daily living and mobility. If your new condition has not meant you've got worse or better since your award then you don't need to report a change.

I have been on PIP for over four years now and I have never had my score change despite changes in my health. I would like to know what the site is that Haz uses. Despite my mobility getting worse and changes in my daily activities I was still given the same score and award. My last assessment was a telephone consultation due to covid19. I have an underactive thyroid, osteoarthritis, arrhythmia Chronic Asthma and depression along with the fybromyalgia and have difficulty talking to anyone due to brain fogand my memory seems to be affected as well. I was told by my doctor that I have Bursitis over a telephone consultation. No examination, x-rays or bloods done. He just sent a prescription for a weeks anti inflammatory pills. This pain is still there months down the line. You could try again maybe you will be better assessed than me.

PIP in the UK is in the process of being changed to Adult Disability Payment. You have to complete the form and inform how FM has added to needs. I have just completed mine. I have been changed to ADP and received the booklet again to update how things have changed or if they are just the same. Mine has just been sent back a couple of weeks ago and I haven't heard anything back yet.
