I call these “adrenaline rushes”. Anyway that’s what it feels like to me. I have been to endocrinologist and they pronounce me entirely normal. I was sure they would find something out of whack. Frankly I’ve just stopped talking about it because it gets me nowhere. I get them early in the morning every day. I guess it’s my “wake up” call. It’s sometimes very early and there’s no going back to sleep. Then I get them now and then through the day. Like others, mine tend to be when I am quiet, trying to rest, relax or watching tv. It starts in the pit of my stomach and radiates down my legs and up my body. My head , for this has not been involved.
Just one more crazy disturbing symptom.
