Zocor and synthroid

Like many posts describing side effects, I was not sure that all the new little health-related issues I've been noticing were connected to taking Zocor. I'm thinking that perhaps my issues are related to the drug, especially since the only other drug I take is Levothyroxine (for hypo-active thyroid). I have been on the generic for two months. (I'm a 39 year old female.)

In the first month, my total cholesterol score was 278. After taking it for one month with no change in diet or physical activity, it reduced to 207. So, the drug does work! Now I need to determine if the cost is worth it.

In the past week, I've noticed several of the side effects listed in some of the posts: sharp pain in knee (feels like there is a paring knife in it!); lower back pain; joints creaking and popping; skin on tips, sides, and underneath of fingers kind of blistering-hardening and peeling off; brain fog in the morning; difficulty maintaining a deep sleep; crazy dreams; general increase in skin blemishes; heartburn; loose bowel movements; and increased sinus congestion.
