I have a swollen lymph node on the back of my head near my right ear. it always swells right before my period. is that normal?

Probably: You may watch and wait. You may feel the node every couple of weeks, outside the time before your period, if the lymph gland doubles in size, becomes painful, ulcerates, or other nodes become enlarged, or you develop fever, you should see a doctor. 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. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
