stay calm, take deep breaths. try to pat your chest. if your chest hurts when you pat it or when you take the deep breaths then its getting seriouse.ive had chest pains too all of the sudden on ocasions. it doesnt hurt for a long time nor does it constantly hurt so its probably something minor. in any case check for symptoms and see if you find anything.tell your parrents if it keeps hurting and if some symptoms apply to you.
