im 14 and i've been feeling alot of pain in my shoulder and back bone
and i've taken panamax (a pill that gets rid of pain)
and then i have this really bad pain in my chest
is it possible i have bone cancer?
i got panamax from the chemist

Mate, it could be anything from small nerve damage to a tumor. Best advice, go see your Doctor. He'll know what it is, if not there and then, he will after a few tests. Don't get worked up, I'm sure you'll be fine.

Only a doctor will know. You should get to one right away. Where did you get the panamax from?
