Bob, my husband, is usually a happy, active, positive man of 71, with heart disease, though. He has had 2 treatments of antibiotics and steroid pills since early December 2017 for treatment of bronchitis. He has seen his Doctor and he is still very ill. Symptoms are fatigue, body aches, a deep feeling of dread for his health. Also, he is a colon cancer survivor of 21 years. How do I pinpoint what he I feeling? Thanks. Beth
