I also have extreme gas
all through out my body. Even sometimes in my upper arms. I went to the hospital twice and had many cardiac tests including stress test, catscan, chest xray, chest ultra scan. I had blood work, and organ ultra scan. My GI doctor doesn't know what is causing this so does not offer a cure. I live on gas X, tums, Gaviscon, and nexium. Nothing helps. I eat bread, vanilla activa yogart, plain rice, plain potato, vanilla ice cream.
