My husband, age 63, in very good physical health-a farmer, has been taking a couple of short naps every day for the last few months and complains of a dull ache over his left chest, and low energy. He just had a physical and his scores are great for cholesterol and blood pressure although he is taking 10 mg hydrochlorothyosine and 20mg of simvastatin per day. He just finished two months of terbinafine. He just saw the doctor two weeks ago and these symptoms have been going on for a few months. We are both puzzled the doctor did t have any answers, said his heart is fine. What should we watch for?
