All I can say is ladies that in 2009, I was like you. I was in pain all over, every muscle, every joint, all the time. I was permanently exhausted and yet slept badly, sometimes very badly. My thoughts were so disjointed that I could not complete a sentence, I stopped recognising people I actually knew well, my memory was shot, I had forgotten how to drive (suddenly on a major road - very scary), I would get up in the morning, come downstairs (the only time I tackled the stairs in a day) and would sit down exhausted.
I was diagnosed with CFS by a consultant and this was confirmed by my GP. I was basically put on the scrapheap, offered antidepressants and, when I turned them down, sent away.
This morning I have walked for two miles to pick up a bike and then cycled for ten miles. If it wasn't raining now where I am, I would be gardening. Tomorrow I will be back at work.
I did not have CFS at all. I had a vitamin B 12 deficiency, coupled with severe vitamin D and ferritin (stored iron) deficiencies. All the doctors I had seen said that my test results were 'normal'. In desperation, I tapped into internet resources and, although it has been a fight, I am now probably 80% recovered.
If anyone would like to share their blood test results, I would be happy to help.
