After 3 months of taking Simvastin my numbers improved significantly. I have not experienced any type of pain or discomfort. However, apparently a fair number of women have difficulties when taking this drug. This may warrant some type of investigation.

During the time that I took Lipitor I experienced pain in my hands and my wrists. My legs would twitch and my calves were sore constantly. I am no longer taking the drug. I am now watching my diet closely to ensure that I will not have to take it again.
