Heel bursitis is mostly known as posterior heel bursitis. There is no simplest way to determine posterior heel bursitis, and it needs to be judged based on the patient’s symptoms, signs, and imaging tests. Posterior heel bursitis is a sterile inflammation of the bursa at the root of the foot, which is mostly caused by ill-fitting shoes, too hard and tight shoe uppers, high activity and too much friction. It is often characterized by pain in the root of the foot, flushing, localized elevated skin temperature, and pain on palpation but mostly without bony prominence. Heel bursitis pain is limited to the heel, there is no fever and cold and other systemic symptoms, the condition is relatively mild. X-ray examination of the ankle joint may show that the posterior translucent triangle disappears or is not clear. If there is long-term pain in the heel without relief, it is recommended to consult a doctor in time to clarify the diagnosis and treatment under the guidance of the doctor.
