I've been having pain under my left rib cage for several months now. At first, it would go away for awhile and then come back, but now it is basically constant. Burning pain in a distinct spot. I also have sporadic burning pain under my left breast area. Sometimes my back hurts along the same line as my front rib pain. I also have the same burning pain right above my navel. I thought it might be an ulcer, but when I started having pain in more than one area, I'm not so sure. My doctor gave me Protonix but it doesn't seem to work. Does anyone have any advice or ideas? Thanks in advance.
