Hello,
I'm 22 years old and a smoker for about 5 years (1 pack/day). for about 3 weeks now i suffer from chest pain/disscomfort especially at the ribs just over my stomach. As the days pass it becomes more persistent. i went to hospital and i did a chest x-ray, blood tests and check my heart too but they found nothing and told me just to take painkillers and it will stop soon, but it didn't.

Do you have any suggestions? should i worry?

p.s. i quit smoking just when this started (20 days ago). i have no cough, no fever, only some headaches once in a while. I have no cancer history in my family.

Thank you.
