What constitutes a change in circumstance?

From my experience a change of circumstances varies depending on the benefit you are claiming.

Hello Jim. Yes I knew it might but as my illness is so very variable not only day to day but person to person and having asked lots and lots of suffers in the various support groups we all seem to be in the common theme is one of normal test results but still suffering the illness.i have read peer reviews papers and found that too so I don't see that I have a c of c in any way shape or form and indeed have new symptoms which are related but could be a short term thing or maybe a long term or recurring thing but overall no change in what I can or can't do and no alleviation of symptoms and related pain.I only wish it would go away but it won't . In the long term ,and after 20years of it what is the long term really, the only option is to treat with pain relief which doesn't always helps anyway.so the Cof C thing is adding to the stress for a lot of people i would have thought...its a mine field of thinking..oh if I have a good day does that mean its a Cof C but them the next day conditions worsen and you are in a bad flare up YET again...
