Recently prescribed hydrocortisone ( 10mg @ 9 am, 5mg @ 12 pm, 5mg @ 5pm) for low cortisol after a short synacthen test, waiting over a month so far for results of thyroid test. I have less energy than ever, dizzy, lightheaded, blood pressure 102/52 today, barely conscious most of the time. Endocrinologist on holiday and GP says he doesn t know anything about this type of illness. Don t know where to get help.
