I have taken Nexium 40 for 2 weeks now and have an unexplainable itch around my neck continuing downward, also a dry, acidy sensatiion in the back of my mouth. I thought drinking water would sooth it but it does not. As well, my eyes feel unpleasantly moist though are not red. Unfortunately I have bought a supply for 3 months since I go overseas but will happily destroy it and find a different way to help with my unexplainable breathing difficulty for which no cause has been found after Heart, Lung and endescopy testing
