MJ,
Its very interesting to hear you have similar symptoms as me. These are very similar to what I used to experience. Unfortunately, I have taken some what of a set back and no no longer have the energy experiences and also don’t have the flushing in my hands and feet as often. (I’d take these back any day compared to what I experience now). I have a theory on why this might be happening. I think there are actually are 2 different scenarios why hands and feet might get cold. 1) would be that you have overall constriction caused by hormones or excessive response to hormones. 2) You are not having access hormone realize, however your autonomic nervous system decided to stop constricting the large veins and arteries, therefore there is less circulation going to the entire body. In this instance I think the heart can virtually beat as fast and hard as it wants but without good constriction in the vessels close to it the heart, blood is not able to make it with much force to the rest of the body. I think the second scenario is what I am currently experiencing for the past month. It stinks.
