For the past 3 weeks my husband has experienced a dull pain, lasting 7 seconds a couple of times a day just above his heart. After visiting his primary care doc, emergency room for tests--EKG, chest x-ray, blood work, which were all clear, he has been advised to see a cardiologist, which we will do. Wondering if could be a side affect of Levothyroxine, Simvastatin or Slo Niacin which he has been taking for years.
