The bottom of my feet hurt at the ball of my foot close to my toes. It is like stabbing pains. What painkillers can I take?

See a doctor. Pain is the body's way to let you know something is wrong, and might need attention. Causes of pain as you describe might be a neuroma, arthritis, or bone injury. Antiinflammatories might help, but you might need something more effective than over-the -counter, such as an injection of steroid. Treatment varies depending on the actual diagnosis.
