question: I'm receiving chemo. 2 days ago I got a burning pain in the eigastric area and thought it was gas. The pain has gotten more severe. Now I can't stand up straight or lie on my left side. The pain seems to be localized in 2 areas, just under my left rib nearly in between my ribs and just below my waist and to the right. The lower pain is in the approimate area where I was told it was pain from ovulation. The pain radiates to my back when it is most severe. Antacids have not helped. The only thing that helps is a heating pad. With the pad the pain is tolerable when I don't move. Without the heating pad it is difficult to tolerate any position.
