PI have MS, my worse symptoms being fatigue and weakness. I have hadit since 1988. Within the last few month I have had a great deal more fatigue than before, and more weakness in my legs, and pain and stiffness in my hands, especially in my finger . But the most extreme symptom of SOMETHING IS SERIOUS EXTREME SWEATING . It just starts when I do some kind of activity. It starts quickly with the smallest of activity, it increases until I stop the activity when it ceases rather quickly. The sweating begins around the the top my head, drenching my hair and face, continuing down toward my hips, the amount of sweat in volume decreasing as it continues down my body, just about stopping on my legs and feet. I m 64 female. Hope you can help me. I have had a thorough blood test last week, but I won t know any results until late next week. Can you tell me if it sounds like tyroid problems! I won t hold you at it ! What would the possible problems be ? How is it treated? --Ann (910) 824-6832

Hi, I passed carefully through your question and would explain that your symptoms could be related to thyroid gland dysfunction. Other possible causes would be: autonomic nervous system dysfunction, chronic fatigue syn Chat Doctor.  For this reason, I would recommend consulting with your attending physician for a physical exam and some tests: - complete blood count for anemia- PCR, ESR for inflammation- thyroid hormone levels for thyroid gland dysfunction- vitamin D and vitamin E plasma levels for possible deficiency.  Amitriptyline could help improve your situation, if all the above tests result normal.  Hope I have answered your query. Let me know if I can assist you further.
