Hello everyone, I need advice. I'm a 20 year old female, 5"4 and about 110lbs. I'm not the most active or healthy eating person, but I'm fairly well. Lately I've been experiencing something strange. It's difficult to explain. I get this sensation in my chest like my heart is "stopping" or what feels like a long pause. Followed by a blood rush to my head that makes my ears ring and I get warm. Meanwhile, my chest and arms experience a strange tingling. After those few moments, it feels like my hearts beating very faint. Then I have the urge to gasp or cough for it to go back to normal. It's quite frightening, it makes me feel as if my heart will stop. Being in the medical field, I thought about anxiety and stress and what not..but confidently narrowed that out. This is a real feeling, usually comes up unexpectedly. Definitely doesn't seem like something my mind is doing or something I am over reacting to. It's starting to concern me a little, because it's happen more often and it's causing problems with my routine schedule. Any advice is greatly appreciated. Thank you
