is my lipitor making me sick?

I lam a 55 year old female and since August of this year, I have been having lightheadedness, heart palpitations, high blood pressure, nausia, creaking joints, etc. You name it I have it.  My Dr. switched my blood pressure med from Plendil to Antenol and Diovan, and I am currently taking lipitor.  I asked my Dr. if it could be the Blood Pressure meds. causing any of these symptoms & he says no.  I was diagnosed with a multi nodular goiter on my thyroid and am going for surgery tomorrow to have the right thyroid removed.  My Dr. says to wait till after the surgery to see if the symptoms cease.  I am concerned about the lipitor as I have been taking it for 6 years and have checked several other sites and find some of my symptoms can be caused by lipitor.  Any help would be appreciated.  I am tired of being sick.
