The biggest single cause of heel pain in most adults is plantar fasciitis; inflammation of the connective tissue.  In each foot, you have a fibrous band of connective tissue known as the plantar fascia, which starts at the heel and runs across the arch to the base of your toes.

Ingrown toenails most commonly occur on the big toe and are caused by pressure that drives the edge of the nail into the surrounding skin.  Ingrown toenails can result from improper nail trimming, injuries, or fungal infections and can be very painful.

A bunion is a bump that appears inside the foot, near the big toe.  Bunions form when the toe moves out of place.  The bump is a bone protruding towards the inside of the big foot.  If untreated, bunions can cause sever pain and even hinder walking abilities.

Ankle pain may be caused from an unnatural twisting or force on the ankle or bones, or may be due to a ankle sprain.  The ankle pain may cause redness, swelling, stiffness and warmth in the affected area.   Other possible problems can include arthritis, or tendinitis.
