Have you been drinking a lot of caffeine or are you under a lot of stress
, do you smoke? All these things can cause palpitations. Palpitations are nothing to worry about usually unless you have heart disease
. Everyone has them but most don't even realize they are having them. They are not dangerous as long as they keep going away. If you are having a lot of caffeine, stress or smoke and you cut back on those things they should go away. Try to ignore them, they are not serious, just irritating.
