Hi .I have been on sirolimus for three weeks. Together with having lam I have a hiatus hernia and gerd. I was also treated for an ulcer previously. I am on 40mg of nexium twice daily.Since starting sirolimus I have lots of pain in my tummy and I find the nexium is not helping me at all with the gerd.It has actually gotten worse.Has anyone experience this and can give any advice.thanks
