Just diagnosed with empty sella, pit. atrophy and adrenal insufficiency. I gained 20lbs rapidly and am full of fluid. Blurred vision and headaches. I was given prednisone 2.5mgs. 2x daily. When I take only one pill [2.5] I have episodes of hot/sweating, dizzy spells,frequent urination, chest pains, worsening rapid heart rate with fluttering, stomach cramps, over acid stomach/reflux and distention,feelings of fear etc...My doc has told me hydrocortisone is for bad adrenals and mine is pituitary and it binds salt, so I need pred. I have low sodium and low bp and temps which are now all over the place too. A fever, then 5 min later, low. Also, Hashimoto's and low thyroid and on Armour. Please, advise. What can I do?
