Sales numbers symptoms and conditions

I am 62 years old and I was taking Lipitor 10 mg for the last 5 years in New York. When I moved to California the new doctor switched to Lipitor 20mg and I started to have strange side effects. After a pause of two days, I restarted and the symptoms were worse: my muscle in the upper arms, and my calves were hurting and week, my back ached, my head was empty nad I felt dizzy all the time.
I stopped two days ago and today I had blood in my urine. What's happening? should I go on any medication at all to lower my cholesterol? My new test was: 179 Cholesterol
HDL 71
LDL 95
I am too scared to start any other drugs like Crstor or Niaspan as I was recommended.
Please advise,
