Oh geez! You do describe the classic symptoms of an injured rib or injury to the muscules surrounding/the covering of, your rib cage, Kay. With a fractured rib the pain is quite severe and usually doesn't subside then return. Bending, reaching, twisting is almost impossible to do without SCREAMING!! Do you remember doing anything particularly strenous in the past several days that could have strained a muscle? I've had the same type of symptoms myself before, but mine originate from just under my shoulder blade. Taking a deep breath is almost impossible! Are you sure the pain is originating in the front ribcage? A pinched nerve in your back, shoulder/scapula can cause the same symptoms too! Lung infection or infection of the lining of the lung sac, can also cause such pain. Joycenalex described it perfectly. AND it could be gas!! Yes, what we officially refer to in the medical profession as a floating f---! For that, we recommend laying on your side to facilitate the passage of the "air!" Seriously, it does sound from your description that it could be an injured rib!! The only way to know for sure, really, if you have fx'd a rib, is to get it x-rayed! If it's still bothering you tomorrow, you should ask your Mom if she can take you to get it checked out by a physician! Symptoms like yours, suffered over such a period of time, should definitely be looked into! (I'm not a Dr...I just play one on Pet Talk...JUST KIDDING! I know how uncomfortable you're feeling; try and lay or sit quietly in a position most comfortable. Sometimes holding a soft pillow up under your ribcage or behind your back can lessen the discomfort. I hope you feel better, Kay!! Don't let it go much longer without getting it checked out, ok?? {{{hugs}}}
