breathing easier but acid indigestion and reflux. Cramp. I stopped taking the seretide evohaler and the terrible acid continued but got easier. The cramp has gone, thank goodness as one muscle would cramp one way and the other would cramp the other, in a leg it is so painful. I now find after having been off Seretide for a year and thinking that the acid had settled that I have aa stomach ulcer. Before going on the Seretide I didnt know what indigestion was.
