In May of this past year began not feeling well. Major heat intolerance, foggy head, headaches, tingling back, stiff neck, racing heart, near fainting episodes, an arythmia that kept me overnight in the ER and very low blood pressure and heart rate (lying down). In addition, developed GERD, stomach bloating, constipation and asthma. Been to many docs had the full cardio workup, gastro workup and now into the full neuro workup in which doc said she was shocked my mri didn't show for ms. Presently, when I stand up my heart races and feel lightheaded with blurry vision yet have never fainted. My hand coordination is not what is used to be with muscle loss,overall weakness,anxiety that seems to come on without my control, numbness and tingling limbs, cold feet and hands severe exercise intolerance, body temperature regulations issues and severe fatigue. Last night had an adrenaline rush that suddenly made my body burn up in addition to sweating and rapid heart rate. I've had so many tests and ruled out many things but wondering if this sounds like POTS at all? I am a 30 year old female who has given up being a head girls basketball coach because this has so completely knocked me on my butt and am barely able to teach. Frustrated and wondering if anyone has any insight? Whether I need to go back to my cardio or discuss with neuro? Thanks
