Chronic fatigue syndrome (CFS) is defined as severe fatigue that lasts for more than 6 months combined with at least 4 of these additional symptoms: headaches; tender lymph nodes; sore throat; muscle pain; pain or aches in several joints without swelling or redness; not being able to concentrate, focus, or remember; feeling tired even if sleeping; feeling discomfort or "out-of-sorts" after physical exertion. In your case fatigue lasts 3 months and you have only 2 additional symptoms (tiredness and sleepiness). So, it is unlikely that you have CFS.
According to your age, symptoms (fatigue, sleepiness, tingling sensations all over the body and all normal laboratory results ) indicate you could possibly be experiencing neurasthenia (a kind of neurotic disorder).
