Hi, My 83 year old mother is taking pravastatin 10 day for high cholestral.It s @239.She is petite 5 3 &105lbs.She s been taking it for about 3 yrs.She is experiencing muscle spasms extremely excruciating in her neck&shoulders also all the way down her left arm,headache,nausea&her left foot isn t picking up properly when she walks so she went to the hospital.They have done an MRI,CT SCAN, BLOOD TESTS,CHEST XRAY&now a stress test.The results have been negative on the tests.I was wondering if the pravastatin could be the cause of this?I ve read online that it could but the doctor says no.
