I Have Been Experiencing Weakness And Off Balance Feelings For

I have been experiencing weakness and off balance feelings for over a month. My cardiologist told me to stop taking vitamins and the simvastatin once a day. Just to continue with Icaps, Areds for the wet MD in one eye. He also wants me to have a field of vision test and (I go to a retina doc for the right eye for shots- had one so far) and to see a neurologist. I feel better after 3 days of no meds but the Icaps. Could the statin cause the weakness and off balance feelings?? Ty.
