In some situations, general health conditions can bring about heel pain.
- Rheumatoid arthritis and other forms of arthritis, including gout, which usually manifests itself in the big toe joint, can cause heel discomfort in some cases.
- Heel pain may also be the result of an inflamed bursa (bursitis), a small, irritated sack of fluid; a neuroma (a nerve growth); or other soft-tissue growth. Such heel pain may be associated with a heel spur, or may mimic the pain of a heel spur.
- Haglund's deformity ("pump bump") is a bone enlargement at the back of the heel bone, in the area where the Achilles tendon attaches to the bone. This sometimes painful deformity generally is the result of bursitis caused by pressure against the shoe, and can be aggravated by the height or stitching of a heel counter of a particular shoe.
- Pain at the back of the heel is associated with inflammation of the achilles tendon as it runs behind the ankle and inserts on the back surface of the heel bone. The inflammation is called achilles tendonitis. It is common among people who run and walk a lot and have tight tendons. The condition occurs when the tendon is strained over time, causing the fibers to tear or stretch along its length, or at its insertion on to the heel bone. This leads to inflammation, pain, and the possible growth of a bone spur on the back of the heel bone. The inflammation is aggravated by the chronic irritation that sometimes accompanies an active lifestyle and certain activities that strain an already tight tendon.
- Bone bruises are common heel injuries. A bone bruise or contusion is an inflammation of the tissues that cover the heel bone. A bone bruise is a sharply painful injury caused by the direct impact of a hard object or surface on the foot.
- Stress fractures of the heel bone also can occur, but these are less frequent.
