I've had ME since 1989, I was very severe and bedbound for years, made some progress but still remained at the moderate/severe scale until 2012 when I relapsed and since then I've been severe/housebound with some improvement but still need a lot of practical support and door to door transport to go anywhere.
I been ill long enough to see these "breakthroughs" come and go, yet never has there been any effective treatment to come out of it. I took part in the SPECT scan research at Middlesex Hospital that looked at blood flow in the brain. That was supposed to be another great breakthrough which "proved" ME really existed, but guess what? Nothing of any significance came out of that research except maybe one tiny piece of the puzzle that might explain something or might not. That was in 1993, so 20-odd years ago.
Then there was the XMRV mouse virus a few times ago, whatever happened to that?? People were claiming to be "XMRV positive" but that one was debunked and fell into obscurity.
If anyone wants to be free of ME/CFS then look no further. Because I absolutely hate it. I've done just about everything from attending the Homeopathic Hospital as it once was, to the CFS clinic at Kings College. So forgive my cynicism. Don't get me wrong, research is important and valuable. I've even donated my DNA for research purposes. But what is actually going to make a difference to the lives of those who have this condition? So far there's been nothing.
