When I wore the BP monitor for 24 hours it did show my pressure quite low before I woke up, perhaps there's a relationship there. There a lots of people over the internet trying to resolve this odd sensation.
I am awakened at night occasionally with this. I have never found out what it's like my cell pone is going off in my chest.
it would appear that quite a number of people seem to feel these shiverings. I know if I am laying down VERY tired and get those feeling, if I stand up and start to walk around they disappear in less than a minute.
You are not alone. My wife has it too, but she says, there is ants moving around in my chest and/or neck. She went to see the doctor, but he is stumped and suggested tests, however, didn't specify what kind of tests. She doesn't have your other health problems that you alluded to so, therfore, I doubt that it is related to those.
how odd, I replied to a thread in the expert forum and it came into here?
