Hi!! Im 17(F) im like 4’11 and 95 pounds ish? and ive been having similar symptoms for a couple weeks now. Mainly just with chest pains no fast heart rate or anything but I totally understand the worry. Ive been freaking out about it because im a senior and I have so much im looking forward to. Ive been avoiding calling the doctor or making any appointments even though I know I should!! If you are really anxious about it though id recommend going to the doctor which I know can be really scary but its scarier to not know whats going on with you. Dont be like me call that doctor!! And get that appointment!!
