Hello. I am a fifteen year old boy and for a little over a week now i have been expierncing chest pains and shortness of breath issues. At first it only happened at night but then it started happening at random hours during the day. But anyways the pain has gotten worse and i really dont know how to deal with the feeling of shortness of breath because it keeps freaking me out because it is very uncomfortable and scary. Is there any treatment, medicine or techniques that can help me calm down and help lessen the pain of my chest and shortness of breath? I have been to my doctor and she said it wasnt anything heart related but probably something muscle related under my "breastbone." She said there is really no medicines to help me feel better. Everytime i start getting shortness of breath i feel like im going to have a heart attack. Please give me input on how to control and manage the situtation.
