Hey Tan, I had nasty nasty Bronchitis recently, and chest pain with that - have you been coughing hard lately? I got the really bad chest pain before I got the chesty cough, so I didn't realise I had a chest infection - I just freaked out cos it hurt to breathe!
I'd still head to a dr, even though it's a pain, cos trust me, if you have what I had, you seriously want to nip this in the bud!!
