Congestive heart failure symptoms symptoms and conditions

I am a 46 y/o male whom took lipitor 20mg for about 10 days. It was the first medication taken for me aside from occasional antibiotics. Within a week I began to develop severe nausea, weakness, postural dizziness and worst of all, chest pain at rest! I took my last dose last Saturday 8/9/08. Because of the chest pain, I went to the ER on 8/10/08 and discharged the next day after I ruled out for an MI and a negative exercise stress test. My chest pain recurred on 8/12. This AM awoke with nausea, dizziness and chest pain again. I'm going to have an adenosine stress test this PM. I consulted a pharmacologist yesterday about the metabolism of Lipitor and she told me indeed these side effects are not uncommon and in my case, Lipitor will not be eliminated from my body until probably this Sunday or early next week. Anyone experience what I'm feeling?
