get a second opinion from another medical professional. get copies of your records including your lab tests and bring them to this next diagnostic visit. remember you have only had one opinion. one that you do not agree with so it is up to you to seek another opinion when you feel that you may be misdiagnosed. unfortunately fatigue is such a vague symptom (thousands of medical conditions can result in fatigue) that it would be impossible to blindly sort the diagnostic considerations blindly over the internet.
possible chronic fatigue misdiagnosis? constantly exhausted and unintentional weight loss of about 11lbs in 5 weeks! . i have been diagnosed with chronic fatigue syndrome after a whole host of tests were done. i do not actually think that i have cfs as i do not experience any cognitive /muscle problems etc- i only suffer from debilitating fatigue! . since my discharge i have lost weight rapidly (11lbs in 5 weeks which for a 20yr old female who was about 130lbs to begin with is quite significant! ). this combined with the fact that my only cfs symptom is fatigue makes me think that i have been misdiagnosed.
