I've sprained my ankle & need to know if i should see a doctor?

Depends: If you can walk on that ankle, there is no swelling, no discoloration of skin, no abrasions and no weakness in the leg, you need not see a 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.
