The last three days I've had a sharp pain under my right rib cage. It hurts to breathe, and it hurts when i'm just sitting. About three to five times a day, I'll get a really really sharp pain under my rib cage and it feels like a big bubble that will only go away if i take a really deep breath, but it hurts too much to breathe or even move. It happens if I laugh or if I'm laying down and switch positions too fast.. I can't take a deep breath laying down either or the "bubble" will come. I can't breathe hardly at all when it happens. i have to take really quick and short breaths.. it has happened before, but never as bad as the last three days and it's never left me sore.
