Welchol and fingers

Just started Welchol after trying Lipitor & others. Have now developed severe vertigo & my right upper arm is killing me. I can't drink ANY alcohol because it makes me violently ill, almost to the point of throwing up, My doc says this drug is non-systemic & says I should have a brain scan...I stopped taking it 3 days ago-arm pain is gone but not the vertigo yet...I'll have to weigh my options of going back on it again.
Has anyone else had dizziness & lightheadedness from this?

Teriible lower back pain and hip pain each morning after sleeping. I am not one to lie awake at night, and typically do not wake up all night. When I "try" to get out of bed in the morning, I can hardley move. Now my fingers are stiff and I can barely bend them, or if I have bent them into a fist during the night, I have terrible trouble opening my hand. Ususally requires the use of the other hand to open or close my fingers. Have alo noticed of late, muscle pain, I have been going to a health club abd haven't worked out in years, but after 4 months, you'd think the muscles wouldn't still be tender...
