Need to examine: The symptoms you described suggest infection/inflammation of the breast. It is imperative that you see a doctor for an evaluation to get the proper treatment. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.
