Small fluid-filled sacs, called bursae, help cushion your joints, bones, and tendons. Repeated motion or friction from shoes can make them swell. In the foot, your toes or heel might get red, swollen, and painful. Ice, padding, and non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, and naproxen can help. Severe cases may need a corticosteroid shot or even surgery.
