I have taken Lipitor for more than 15 years. Since 12/29/16 I have been experiencing chest pain sometimes so severe that my neck, arms, wrists and back hurt. My wife rubs and pats my back and sometimes I pace the floor and after a few belches, it will subside. When the severe attack happens, it can last for up to 2 hours. It only happens at night when I lie down - usually around 11 pm to midnight. It happens on average of 4 times per week with one of the episodes being a severe episode each week. I have had all of the heart tests - my heart is fine. I have had several GI tests and the gastroenterologist says all tests are good. They said it was GERD. I have had GERD and it has been under control for years. But I never experienced this type of pain. I did everything asked of me to help with this such as - raising my bed, not eating before bed (the pain begins about 6 to 7 hours after I eat), on two different scripts for antacid, staying away from acid and gassy foods... Now the doctor is saying it must be a reaction to Lipitor. I never had a reaction to this drug before. Can it build up in your system and become a problem all of sudden years later? My quality of life has gone right downhill. Please help
