Recently, my heart is very uncomfortable, feeling chest tightness, shortness of breath, nervousness, restlessness, burning sensation in the left side of the heart near the armpit, sometimes feeling sharp pain or sweating, not eating well, being hungry. I can't stand it, I feel tired after eating, and it's hard to go to sleep. So the doctor told me what is the cause of female chest pain and heart ache?

I am 17 years old this year. Recently, I often have a sharp pain in my heart (every time I feel a little choked when I breathe, or when I roll over, I can't breathe). I know it's normal to have cramps every other day, but I'm feeling it most of the time now. So, the doctor asked me, what is the frequent throbbing pain in the heart?
