I presume that you actually meant the drug livalo which is a statin used to lower the cholesterol
levels.This drug does have some unwanted effects on the muscles.It could cause muscle cramps
and also sometimes muscle breakdown and renal failure
.There is a pretty good chance that the muscle pains, that you have been experiencing may be secondary to this drug.This is again supported by the fact that you had relief ,while not on this drug.Livolol is also better to be avoided in thyroid disease
may not have anything to do with the drug.
To conclude it may be advisable for you to approach your doctor and ask for a change in the drug, as you are finding it difficult to tolerate.
