I have tested positive for neurally mediated hypotension. Dizziness is one of my main symptoms. But there seems to be something different happening. Or maybe it’s just worsening of my existing symptoms ? I’ve had ME for about 5 years and although I’ve often had to lie down in order to avoid fainting, I never came this close as I have the past 7-10 days. It happened 3 times. Once just after getting up and walking a few steps, and twice after looking up to the ceiling (to set my air conditioning, at the top of my stairs, close to the ceiling). After only 2-3 seconds of looking up, I start seeing stars/darkness and have to sit very fast or I know I will lose consciousness. I have had some cardio pulmonary testing done lately that triggered PEM for about 7 days but only one episode happened while I was recuperating. Any thoughts on what I could ask my doctor to check ? I’ve been tested again and again in the cardio department and my heart is fine. I do have bradycardia and low blood pressure, which aren’t helping. The cardiologist I saw recently said he wasn’t concerned about my bradycardia, unless I have episodes of fainting. Maybe this is where I am now ?
