Wearing shoes that don't fit well, striking the feet on hard surfaces and being overweight may cause a sore or painful heel, explains Healthline. Heel spurs and plantar fasciitis also cause the heel to hurt.
Heel spurs are common in patients with obesity and athletes who run or jog regularly, according to Healthline. The spurs occur as a result of excessive stretching of the lining that covers the heel, resulting in pieces of the lining breaking off.
Plantar fasciitis develops by wearing shoes that don't fit well or from inflammation of the tissue that connects the heel to the ball of the foot, explains Healthline. Achilles tendinitis develops due to inflammation of Achilles tendon, located at the back of the heel, and may also cause sore heels.
Excessive pronation as a result of continuous ligament and tendon stretching at the back of the heel may result in heel pain, as stated by Healthline. Injuries to the hips, knees or back can alter the way a person walks and eventually lead to this condition.
Resting the feet, using heel cups, wearing night splints and shoes that fit properly, application of ice to the affected area twice a day, and using over-the-counter drugs can aid in alleviating heel pain, advises Healthline. Patients who experience extreme pain, swelling or redness of the heel, or unexpected heel pain should seek immediate medical attention.
