Oh dear Mimi, what does your doctor say about all of this? Could it possibly be like a case of comorbidity, like more than one illness, all at the same time? I hear that happens sometimes. What if your doctor is really busy & sometimes doesn't see everything?.....And that thing I said about bending over, yes, like you're touching your toes. I was told, when I felt like I was going to faint, to hang my head down between my knees. It worked. So I found out later that my brain needed the oxygen in the blood.
