I have been taking Zelnorm for about a year and a half. At one point I went to the Dr. complaining about chest pain. They said (because of my age, I was 28 then) that I had inflammed cartlidge in my chest and prescribed me Celebrex (which did nothing). I tried to get my Zelnorm refilled today and I was told it was pulled off the US market due to Heart Attack, Stroke, and Angina risks. I am not sure what to do. I called my doctors and none of them are taking it seriously due to my age. Any advise??
