Hi
Welcome to the MedHelp forum!
Extreme fatigue can be due to several causes and though you have had blood tests I am just enumerating the possibilities. It is unlikely to be MS. Extreme fatigue could be due to menopause, premenopause, hormonal disturbances, anemia, diabetes, hypothyroidism, or due to kidney or liver problems. Another possibility is sleep disturbances (like sleep apnea, imbalance of rapid eye and non rapid eye movement sleep etc.). You may sleep your customary 7-8 hours and yet feel fatigued. You need sleep studies to rule this out. Other possibilities are chronic fatigue syndrome, depression, low Vit b12, low iron, low calcium, sodium and potassium. Hyperthyroidism too causes increased sweating and tiredness. Postviral fatigue syndrome is another possibility. Persisting EBV infection or mono can also be the cause. A comprehensive investigation is required keeping all the points in mind. Do discuss this with your doctor and get yourself examined.
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP for primary examination followed by proper referral. Take care!
