No, I never recovered after a 2 week virus/flu in 2008 (dd had similar bug at same time). Back and forth to gp, blood tests etc. Eventually told I had post viral fatigue and they could do nothing for me, just go away and get on with it.
Off sick for 6 months then returned on reduced hours after small improvement. Lots of research myself, trying different supplements etc.
2012 moved to a city and asked new GP if I could get re diagnosed as I'd read that PVH is supposed to be a temporary diagnosis.
Got diagnosed with CFS by a infectious and tropical disease consultant. Referred for a set of sessions with an ME/CFS NHS service run by a team of psychologists and physiotherapists.
Advice on pacing, diet, graded exercise etc. Wasn't really appropriate for me as I was working and couldn't apply the pacing in line with my job.
Had a few chats with the psychologist there who very smugly told me that she felt my diagnosis wasn't valid and she thought I was just depressed.
Told me she thought I had repressed grief from my mother dying. I pointed out that my symptoms began in 2008 and mum died in 2011. She sighed and said rudely that there was nothing physically wrong with me.
Since then I haven't bothered doing anything apart from my own research, Facebook groups etc.
So no, NHS has done very little for me!
