O.k. I am a 45 yr. old female I have Hypothyroidism and had a tumor removed from my pituitary gland years ago which resulted in Cushing's disease. As of late I've been exhausted but insomniac at the same time, I am 2 months late and not pregnant. As I type this I'm starting to get really hot and if I stay still long enough I'll get really cold all of the sudden. My tsh and t4 are with in range. Any ideas? Thank you Hope everyone is fine and well.
