Heel spurs and heel pad irritation are the two most common causes of heel pain and is due to overload. Relief is the best treatment. Upon failure of relief, your doctor may inject corticosteroid into the heel, refer you to physical therapy or perform surgery. Both conditions are lengthy and disappear only after several months.
Under the great heel bone is a heel pad that protects the bone against shock when you walk or run. The heel pad acts as an "air bag". If the heel is exposed to many shocks - for example, by running on concrete or numerous hop on a hard surface – the tissue crushes in in the heel pad and there comes pain. The load and the rays towards the toes trigger the pain.
From the large heel bone and out to the toes, you have a wide collection of tendons - called a tendon plate where the foot rests. By overload - for example, by walking or running on hard surfaces – the tendons and can become irritated, resulting in pain. The pain is most pronounced in the morning, just when you get out of bed and decreases when you walk in the foot. The pain is increasing again after some time load. The pain is localized at a particular point about five cm from the back of the heel. The place is sore to pressure. Sometimes - but not always - can form a small bone - a so-called heel spurs.
Both heel spurs and heel pad irritation are due to overload of the micro-damage in the tissue - either in the heel pad, or in the tendon plate.
