Hello, my name is April. I have been loosing stamina and have come to complete fatigue over the last couple months. A week ago I had a spell of light headed ness followed with sweats burning chest and a period of blacking out without passing out. I have since then had continual chest pressure, headaches, high blood pressure, exhaustion and a tightening of the throat with pressure and pain on lower left of my throat above my thyroid. I have had negative results from a thyroid ultrasound, and cat with contrast, thyroid blood work and a full blood work panel. I am on bystoic and it has been keeping my blood pressure low. I am 40 female, on chug and testosterone due to lack of function. I am hypothyroid and take lexapro for mild anxiety. Any thought?
