Nowadays, there is nothing hotter than square dancing and brisk walking, but many elderly people have heel pain after a period of walking sports, not red or swollen, just a walk a jump on the pain. This time to go to the hospital a film, oh, the original is the heel long “bone spurs”, that can not be painful. Is this really the case? Let’s learn more about heel pain. Heel pain is more common in middle-aged and elderly people and those who are heavier, and is a chronic strain on the plantar fascia caused by long-term, continuous, excessive strain on the heel, resulting in chronic inflammation and pain. Heel pain is characterized by a slow onset, localized pain at the beginning of walking, difficulty in walking, pain relief after a few minutes of walking for a short distance, and increased pain after walking for a long distance. It can develop on one or both sides and can be divided into intraheel pain, posterior heel pain, and inferior heel pain, with inferior heel pain being the most common. Lateral X-rays of the heel bone may reveal osteophytes of varying sizes at the anterior edge of the nodes on the bottom surface of the heel bone, i.e., bone spurs. However, the degree of pain in heel pain is not proportional to the size of the heel spur, and those with symptoms may be asymptomatic and those with spurs may be asymptomatic. Nowadays, it is generally believed that heel spurs are only a possible cause of heel pain, and there is no necessary relationship between the two, so it cannot be wrongly considered that heel spurs are equivalent to heel pain. However, once the heel spur is formed, it is bound to form potential irritation to the surrounding tendon membrane and heel fat pad, and the cumulative irritation causes edema and thickening of the tissue around the heel spur, which in turn stimulates the nerve and becomes a potential causative factor for heel pain. Therefore, the chance of plantar fascia strain will increase accordingly with heavy labor, more walking, excessive weight and foot overload, and heel pain is more likely to occur.
