I have been having strange symptoms, mostly fatigue and some pain for 35+ years off and on. the syndrome sort of burned out about 10 years ago and then I had breast cancer with chemo and radiation and it came back but nothing I couldn't handle. A year ago I developed cancer in the other breat and had a mastectomy. A few months later I got pneumonia and couldn't seem to recover from the tiredness. They discovered a viatamin D deficiency and I felt so much better I thought that was it. Several months later the muscle pain and the fatigue came back with a vengeance. That is where I am now.
