If your healthy and all, it's probably nothing.
Definitely get it checked out if you feel like it might be something serious.
It's just that I also am fairly healthy except for needing foot surgery I would say I have no other serious medical issues.
And the point I;m getting at is, throughout my life I always get weird pains over my body, sometimes in my head, sometimes in chest like you, some go away after a day, some go away after a few days, some are sharp pains, some are dull pains, For examply yesterday I got these shooting pains in my head and it happened quite a few times, and I started thinking all sorts of things, etc.. Well i think you get my point.
I for sure can remember some pains I've had in my lungs when I take a deep breathe and it's never been anything serious.
usually I just stresses myself about them and got worried it might be something and then after a few days it went away. Usually if I stopped thinking about it it would go away faster. Now if this chest pain is a severe pain, and it's preventing you from breathing in anyway and/or it has been going on for many many days, then definitley get yourself an appointment with a doctor.
I hope you feel better.
