Yep. All hormones and heart function checked out. Well, hormones r low but no lower than they've been this past year. Actually when this started my salivary cortisol went up. The only thing that was sligtly different than any other blood work I've had is my white blood cell count is slightly low but no doctor was concerned about that. Nothing is standing out. I am going to go to UCLA neurology this week tho and get tested for POTS. Hoping its not that.
