Has anyone else experienced anxiety with persistant palpitations and it feels like your heart is racing but you can't make it calm down? Along with feeling warmer in certain parts of your body, stomach pain, other bodily pains and stuff. Not too long ago I was in the ER for a similar issue and they said I was fine and it was likely anxiety, but it's just driving me into a complete panic here and I can't make it end. Any advice or help would be greatly appriciated.
