Hi, i have 5 small bumps under my left foot and its pain when i walk . the bumps is in black in color and have a thick skin on it?

Possibly: plantar warts. Your dermatologist or podiatrist can check this out for you.

Need to examine: It is not feasible to provide a meaningful opinion without examining you, however your symptoms suggest planter warts. You may try over the counter treatment for warts. If that does not work, it would be useful to 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.
