Need to examine: You may have injured your inside, i.e. inside the vagina and it would not be feasible to provide a meaningful opinion without examining you. You may try doing without sex for a couple of weeks to allow the lesion to a heal. If that does not help, you should see a gynecologist. 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.
