Hi for a long time I've been able to hear/feel my heart thumping away but recently as I lie down in bed it feels like my heart is going to burst out my chest. It only gets like that when I get into bed. No pain with it or anything just generally I feel quite warm when it happens. I hate going to the doctor's so was wondering if anyone has experiences of palpatations or similar. Does this sound normal or is it palpatations and would it be best to get it checked out? I've never yet noticed it do this through the day.
