Hi there, I am new to this... I have been having palpitations for a while now. I have been the doctors and had a 24 hour tape on. The results came back and I have been referred to the hospital. While waiting for the appointment I have been waking up with a heavy tight chest. One night I was lying on the sofa and got a awful pain in the left side of my chest I describe it as a tight spasm. I was unable to move while having the pain but it only lasted 3-4 mins. I am a smoker but really cut down and think today's going to be my quit day. Oh I am a 36 year old female.
