I ve had an issue with sore throat, chest pressure, and overwhelming fatigue for @ 30 years. It seems to be aggravated by stress. I ve been tested for Mono, Strep Throat, etc. We thought we d found an answer when I was diagnosed with a severe vitamin D and B deficiency,as well as being Anemic (anemia runs in my family). I m also a Type II Diabetic with A1C readings of 6.0. It s have toyed with fibromyalgia, but I don t fit the symptoms. Is CFS a possibility? Or, any other suggestions?
