Vytorin is more likely to cause muscle aches/pains than synthroid -- and if the thyroid is out of normal range, the muscle aches may be even worse -- esp if hypothyroid.
Also -- hyopothyroidism causes high cholesterol -- so rather than starting synthroid and cholesterol meds at the same time, usually the thryoid is treated first then cholesterol is re-evaluated.
Holding the synthroid for a few days may be helpful, but you may need to be on some synthroid, perhaps at a lower dose -- follow-up with your doctor on these issues.
I gave blood Friday and just got a call from my Doc saying my thyroid is being over treated and to stop the synthroid. I do not have any numbers yet but will meet with him on Tuesday.
I stopped on my own on Saturday and feel a little better. I had a real bad bout with tremors and anxiety last night but today feel better. I hope it does not take long to get this drug out of my system. I can deal with the pain but the fear and anxiety are crushing.
