Just wondered if lipitor can make you get dizzy and fall.?

Ive been taking lipitor since last summer and twice this past wk i fell , at first i thought maybe i tripped over some yaktraxs that i wear for snow and ice but wondered if i fell first and then the yaktraxs caught on my pants or shoelaces. also, lately ive gotten headaches every day and ive been bruising too but not every day. ive talked to my doctor about the headaches and the bruises but nothing came of it. i saw an endocrinologist but because the tests came back normal she never bothered ordering other tests and now im stick stuck with symptoms that i cant do nothing about cause tests come back normal, i had a bone density test come back high risk but the bone scan was normal and because of that i couldnt get on hormones. im 47, ive been taking stuff like black cohosh and soy stuff and that seems to help. im on my last bottle of lipitor and wondered if i should just take niacin, i lost a lot of weight so my cholesterol went down,do people take cholesterol meds forever?
