For years I have seen a connection between gastric pain/reflux (for me in the expression of extreme hunger/never feeling full) and a very painful right shoulder/arm. All other kinds of pain in my body respond well to NSAIDs or Cox2. This particular pain is different as it does not respond to any of them. I am back on esomeprazole and hope to get both the gastric and the shoulder under control in a few days. But in the meantime... It would have been interesting to hear if this sounds familiar to anyone?
