Had that problem once, doc said its pressure level.yu should chech doc
It feels like my heart stops beating for like a second at times im dizzy and light headed im nauseas and my head aches on the lefthand side, what can it be?
Seems like you've got a bad case of something that I'm not smart enough to know about. Doctors are pretty smart about that kind of stuff though...maybe you should go see one.
This could either be low blood pressure or anxiety . Best to have a check up with a doctor .
