Adrenaline rushes were mentioned in another thread as a hypo symptom. I have had these for aslong as I can remember but they didn't bother me until my thyroid problems surfaced. I've had a few cortisol tests and its been both high and low however this year it was fairly normal but could be slightly higher in the day. For people who are stable on meds... do they improve? I'm not on any meds. Thanku.
