Why can't they find why I am having excess sweating and fatigue.

Hi Anon,
Welcome to EmpowHER and thanks for your question.
Several things could be responsible for our sweating. Autonomic nervous system dysfunction, Heat sensitivity, High norepinephrine, Anxiety and Medications. It's important to see a doctor or have a second opinion as to your sweating and fatigue. Only a physician can determine the cause of your systems.
