Chest pain like ive never had before

[skinns09]

when i take a full breath it reallly hurts when i breathe in and when i breathe out it kills and feels like their are things popping in the center of my chest ( i can feel them ) and the pain is from the center of the chest and spreads left over the heart ( my right side is perfectly fine, no pain). I am also getting an even worse pain that hits me right at the bottom of the ribcage at the side of my body, I also feel a pressure right underneath my heart.

Are these the signs of a pulled muscle in the ribcage, as i do lift heavy objects at work.

Thanks for the help!

What you describe isn't what I've felt with angina or a heart attack.  It does sound like the pains I've had with pleurisy, which is an infection on the outside of the lungs.  If you are lifting heavy things, you may have answered your question.  Pleurisy (I'm not sure of the spelling) usually causes one to feel very tired as well.

Also the pain started in my left shoulder, i thought i threw it out, then the pain moved into my chest, and sometimes i feel it in my neck too if i move the wrong way.

thanks
