So I've Recently Started To Exercise After A Long Time

So I've recently started to exercise after a long time and I just got home from practice and close to my heart it seems feels like it's not right and yesterday I had a game and got hit in the chest a couple times but not super hard but my heart today felt liked it skipped a beat and it scared me so much and we ran a lot a practice as well and idk but it feels like a part of my neck or the tube on the left side of my neck is clogged is that possible?
