I have unexplained weight gain, fatigue, intolerance to heat, blood pressure that is usually normal but does fluctuate to extremes occasionally (separate incidences from 180/110 to 78/54 with symptoms that would be expected to occur at these levels, headaches & nausea occasionally, body temperature consistently low with range 96 - 97.6 celcius. Past history of SLE with membraneous nephritis, in remission 20 years but took Prednisone for 5 years & Cyclophosphamide for 2 years back then. My comprehensive Lupus tests, Kidney tests, Cushings, Carcinoid, & Thyroid tests are all good & normal. My doctors are at a loss.
