I started taking Zocor 6 months ago, switched from Crestor because of muscle weakness. About a month and a half ago started to get fuzzy head and could not sleep thru the night. I awoke up to five times a night and could not go back to sleep. I had tingle feeling on my head above the ears. Sometimes I had to get up from whatever I was doing and walk around and it felt like an “anxiety attack” with a feeling of tightness on the back of the neck. My knees are weak and I can feel them whenever I get up from a chair or getting out of the shower. A few times, I felt sharp pain on my right shoulder blade and my head hurts a lot. Cold and hot flashes mostly at night and sometimes in the morning after the shower and during the day together with the “anxiety attack”. Once in a while I would have warm flush feeling on my face. I also have a few pimples like tiny bumps on my head. I could not carry on my normal daily life for the last month and a half. I could not concentrate on anything except constantly feeling the fuzzy head/head heavy/pressure on my head. I also had a MRI on my head and brain to make sure there are no tumors inside and it came back negative. I just found this website a few days ago and I told my doctor that I am taking myself off of the Zocor for a while. I am feeling at least 50% better already after a few days. I am hoping the rest of the side effects would go away eventually. I feel for you all who have been taking this drug for many years.
