Chest pains

I’m 17 and recently I feel like Ive been having chest pains every now and then. So all day today I feel like my chest feels really heavy or tight, it’s uncomfortable but bearable and I can’t really feel it when I’m distracted. The other day on the way to school I have shooting chest pains for about 5/10 minutes in my chest. Sometimes I’ll often lose my breathe if I turn my head to quickly or something and have to regain it. I’d say I’m pretty health, I go to the gym daily. I live in the uk and it’s pretty hard to get a GP’s appointment at the moment and even then I feel like they won’t take me seriously because I’m so young and there’s nothing they can really do. I don’t want to waste their time as I know people need that appointment more than me and I don’t like creating issues. So my question is, is this normal for a teenager to experience? Could you have any idea what this may be?
