Hypothetical: It is unlikely that the untoward events in your family were due to allergy. You may never need an opioid. If you think you may need one, explain your family history to your doctor. Wish you 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. Get HPV vaccine

Get a skin test: Get your PCP to refer you to detmatology to get skin tested. Until then, any other pain medicine is ok to use
