I have had symptoms for awhile now. Tonight the symptoms are worse. I m having trouble sleeping. Severe fatigue, dehydration, nausea is bad, abdominal discomfort, body pain, feeling cold, and exhausted . I recently received test results for high abnormal cortisol. I m not sure if that would be the cause of these symptoms. I m feeling tension throughout my body. I have been drinking bottles of water and it hasn t helped at all. Is this something I should get checked out at the hospital? Or try and rest and wait and follow up with my primary doctor?
