Heel pain can generally be traced to faulty biomechanics, which places too much stress on the heel bone, ligaments or nerves in the area. Stress could result while walking or jumping on hard surfaces, or from poorly made footwear. Being overweight is also a major contributing factor. Some general health conditions — arthritis, gout, and circulatory problems, for example — also cause heel pain.
Plantar fasciitis is an inflammation of the long band of connective tissue running from the heel to the ball of the foot, resulting in arch and heel pain.
Heel spurs are growths of bone on the underside of the heel bone. They can occur without pain; pain may result when inflammation develops at the point where the spur forms.
Pump bump (Haglund's deformity) is a bone enlargement at the back of the heel bone in the area where the Achilles tendon attaches to the bone. The deformity generally is the result of faulty biomechanics causing increased motion of the heel bone against the shoe counter.
Achilles tendinitis is an irritation and inflammation of the tendon that attaches to the back of the heel bone. Achilles tendinitis can be caused by improper warm up or over-training. It can be treated with ice, rest, aspirin or anti-inflammatory medications. Chronic pain or any swelling should be professionally evaluated.
