Does it work out for you?
Man, that could be everything, even ranging to a heart attack.
The left sid of my chest aches... its a terrible pain, like a hundred needles converging into the center of my chest, just over my ribs. If I cough, the pain kills me. If I raise my arm, the pain is back in full. Argh.
You're probably having muscle spasms. Take some ibuprofen or horse tranquilizers.
