Sally,
I am sorry you are not feeling well.
the doctors cannot do anything about the side effects of our medications. The only way to get relief is to stop taking the medication that causes them.
Perhaps your doctor believes you need to take the calcium channel blocker and that it is in your best interest. Doctors sometimes disagree when interpreting the test results and when choosing what they perceive to be the best treatment option. I don't think you are on this medication because your doctors don't like each other. Their motto is: DO NO HARM.
Please ask your doctor why she thinks you should remain on this medication when your cardiologist does not think you need to. You should not have to put up with the side effects if you find them intolerable. They get worse with warmer weather.
