I have been trying new suppliments for my cardiac problems. Have had bypass twice and now one bypass is closed and I'm having pain in my right chest and right side of neck. Nothing in left side. Began taking niacin, lysine, C, E, B6, B12 and folic acid. Now I have developed restless legs and arms. If anyone has ever had this it will drive you nuts at night when trying to fall asleep. What can be done for restless legs? Can these suppliments cause it?
