I recently saw a doctor at Vanderbilt. They have a dept that specializes in dysautonomia. They are supposedly the best. I had been told that I had pots and wanted to have a second opinion. I am still waiting on my results. I tried to explain to the doctor (like many times before) that I could literally feel my fatigue in my head. Something is happening or not in my brain! It is REAL. I suggested a SPECT scan to see if my blood flow is abnormal. That went over like a lead balloon. Why don't these people listen? The only relief I seem to have is when I am lying down. Does anyone else experience this?
