Hi new here on this forum. I have suffered from GERD for several years now and have been on Prevacid for about 2 1/2 years now. I tried going off of it for a while and was a lost cause....heartburn was back with a vengence. Then I tried the 1/2 dose generic Prevacid (15 mg) but this was not working. I am now on the full dose generic Lanzoprolole (sp?) This also seems not to do the trick. I now have a constant dull muscular pain behind the breast bone that aches throughout the day. This has been going on for well over a week now. I don't know if this is a result of damage to my esophogus or not. I also have been experiencing a lot of heart palpitations. Don't know if these are connected. Anyone else have this type of symptom?
