I have been taking vytorin for a few months now. I have pain in my right arm and bad back pain., but whats worse, I have this terrible pain right in the center of my chest that radiates to my back, and sometimes into my right jaw. I broke out in hives two weeks ago, and I don't know what caused that. I have very high cholesterol, mostly heridity. I am 45 years old, but I am scared of the chest pain I'm having. What do you think?
