I have had pain under my right rib cage for about two months. Its a constant stabbing pain that gets worse as the day goes on. I also have extremely sensitive itchy skin. Anything that touches it feels like its scraping. I have been tested for h pylori and e coli: negative. I have tried prilosec, zantac, apples, apple cider vinegar, papaya, enzymes, magnesium, probiotics but it will not go away. Food tastes weird and I have lost weight. At first the pain was moving around and my stomach would burn but now its just constant under the right rib and i have a lump in my throat,
