This is gonna sound strange but is it possible for a 15 year old to have a hareat attack,Ive been kinda worried if im gonna have one because i had a recent anxiety attack about a year ago and ever since then my heart feels like it beat way to fast at times then goes away . Ive had pain in my chest , arm , and knida the neck but no tinggly sensation in the fingers or uspset stomach.My breathings fine because i play basketball and it hasnt been a problem.I havent been to the doctors but im been thinking about it.But im just puting this out there to see if this is a surious problem or its just lack of water,sleep,or whatever................would really like to know Thanks
