I have been on 10mg of Zocor for 2 years . About 3 months ago , I have developed a trembling in my right hand , at first I took no notice of this , believing it to be because of my age (68) ; two weeks ago I suddenly developed a sore neck , and a pain in my left side (kidney area) , this pain was intense and I woke up shaking and thirsty ; for over a year now I have been suffering from insomnia , waking up after a 3 hour sleep . I am active , exercise with a daily 5 mile walk , and until recently , have enjoyed a good 7 - 8 hour sleep . I do not suffer from artrities , and although my tryglicerite was elevated , my HDL was within 4 and 5 . I cannot understand why my GP put me of this statin . I have now decided to stop taking this drug , what I have read about it has alarmed me .
