Go to a doctor if you haven't already. Chest pains can be very serious. My friend very recently nearly died while he was with me. He was having minor chest pains which turned bad fast, so I took him to the hospital and he had to have immediate surgery on his lungs. Turned out his long collapsed and the pressure was so great that it pushed his organs across his chest. His diaphragm and heart were in the right side of his chest... When the emergency surgery was done the doctor told us he would have died if we waited another hour.
