So i was doing a normal exercise like i do everyday and today was focusing on my arm muscles. However i was doing a single arm cable curl for my bicep and all of a sudden on my left arm when i was doing it, i got a sudden pain in my chest/neck vain left side and then a couple minutes and hours later its still there so i decided to test myself and it typically hurts when i take an extremely deep breath through my nose or a moderate deep breath via my mouth. It hurts like theres a pressure/compaction in a "left vein" that goes through the neck to the left carotid region. Is this something to worry about or will it go away in a couple days?
