I am 38 years old and recently I have been having trouble sleeping. When I do find myself starting to rest I start to feel my heart skiping in the middle of my chest. For the past 2 nights I find my self fighting to sleep and my heart seems to be raceing. This is getting me pretty scared I do have a physical coming up and will be asking the doctor. I wanted to see if anyone had these problems also. I have asking the doctor if I could be premenapausal and she said I am to yound.
