Usually the heel is also clinically known as the heel, heel pain is not necessarily a precursor to a major illness or even caused by a disease, and needs to be judged according to the specific circumstances of the patient. For example, wearing uncomfortable shoes in daily life can easily cause wear and tear of the heel skin, which in turn can cause pain and even bleeding and other manifestations. However, for long-term recurrent heel pain, the initial consideration may be caused by disease. For example, clinically common bone spurs, posterior heel bursitis, heel osteoarthritis, sub talar arthritis, heel osteochondritis, Achilles tendonitis, etc. are basically a manifestation of inflammation, which may be related to long-term excessive wear and tear and strain on the relevant parts. They can be effectively controlled by NSAIDs and glucocorticoids at an early stage, and therefore are not a precursor to a major disease. It should be noted that if the heel pain has been diagnosed as caused by foot disease, but the patient still does not undergo active treatment, or if there is persistent heel pain, etc., surgical treatment is required if necessary. At this point, the condition is relatively serious, and although it is not a precursor to a major illness, it suggests that the disease may be deteriorating. In addition, heel pain may also be a precursor to some major illnesses. For example, heel fractures, malignant tumors of the foot, etc., the situation is relatively serious, if not treated in a timely manner, the patient may develop heel deformity, motor dysfunction, etc., which will have a certain adverse effect on daily walking. It may also be caused by ankylosing spondylitis, gout and other arthritic diseases, when the lesion spreads or pain radiates to the heel, the patient may have painful performance. Since these lesions are prone to joint deformity and disability, prompt medical attention is required for comprehensive treatment.
