I dont know what it is and I am getting nervous and thinking that it might be something serious. What can I do or what do I have to do? Please help me!
Hello, A heart attack would be an exceptional diagnosis considering your young age.  In my opinion, your symptoms could be related to a panic attack.  Nevertheless, I recommend going to the ER for a physical exam, a resting ECG and cardiac enzymes in order to be sure that everything is OK. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
