Heel Pain
Bxp36024
Heel pain is one of the most common forms of foot pain in adults. It often occurs as a result of daily activities and exercise. The heel bone (calcaneus) is the largest bone in the foot and the heel is the first part of the foot to contact the ground during walking.
Two structures located on the bottom (sole) of the foot are primarily associated with heel pain: the plantar fascia, a band of fibrous connective tissue, and the flexor digitorum brevis muscle, which supports the arch and flexes the four small toes.
Normally, as the foot absorbs the weight of the body during walking, the arch begins to flatten and the plantar fascia and the flexor digitorum brevis muscle maintain the arch and stabilize the foot.
Gait abnormalities can cause inflammation of the structures attached to the heel bone, resulting in heel pain. Inflammation of the plantar fascia, called plantar fasciitis , is the most common cause of heel pain.
Plantar fasciitis often causes pain that is more severe following a period of rest (e.g., after sleeping). This condition is also called post-static dyskinesia , which means "pain after rest."
Sometimes, muscle strain and tension (usually on the flexor digitorum brevis) pulls a piece of bone away from the calcaneus, causing a heel  or bone spur . Heel spurs can irritate nerves and cause pain.
Incidence and Prevalence 
Heel pain is most common in active people over the age of 40. This increased prevalence may result from a decrease in the elasticity of the plantar fascia and a slowing of the healing process with age. Heel pain also is relatively common in active children and adolescents between the ages of 8 and 13.
Heel pain occurs in both heels (bilaterally) in less than 30% of cases.
Risk Factors and Causes 
Misalignments  caused by abnormalities in the structure of the feet increase the risk for heel pain. Other risk factors include the following:
Engaging in strenuous exercise (especially repetitive jumping and running)
Obesity
Standing for prolonged periods
Wearing shoes that do not fit properly. To reduce the risk for heel pain, it is important to wear shoes or sneakers that fit correctly and to warm up  properly before exercising.
The  most common cause for heel pain is inflammation of the fibrous connective tissue on the sole of the foot (plantar fasciitis). Other causes include the following:
Achilles tendonitis ( Bone bruises)
Excessive pronation (tendency of the foot to turn inward)
Haglund's deformity (bony growth at the back of the heel that usually occurs when shoes repeatedly aggravate tissue and underlying bone)
Heel spurs (also called bone spurs)
Inflammatory conditions (e.g., ankylosing spondylitis, diffuse idiopathic skeletal hyperostosis, rheumatoid arthritis, bursitis)
Sever's disease (relatively common condition in active growing children and adolescents)
Soft-tissue sarcoma of the foot (rare)
Stress fractures
Tarsa tunnel syndrome ( nerve entrapment that may cause pain on the sole of the foot)


Signs and Symptoms 
Heel pain varies in severity. In most cases of plantar fasciitis, pain is more severe following periods of inactivity (e.g., in the morning), subsides with activity, and increases in severity with prolonged activity. This occurs because inactivity causes the muscles in the foot to tighten, increasing the strain on the plantar fascia and aggravating heel spurs, if they are present. The muscles stretch with mild activity and the heel pain subsides. Prolonged or strenuous activity increases inflammation and the severity of heel pain.
Other symptoms of plantar fasciitis include swelling , redness , and heat .
