In March of 1998, there was a soreness on the right side of the ankle. There was no obvious redness on the outside, and the symptoms were basically relieved after the rest. One year later, when the sprained right heel was accidentally strained during work, he was slightly swollen and painful. An X-ray examination showed that the right tibia was fractured in the local hospital. There was no improvement after the use of the drug. Outpatients were examined by physical examination and X-ray examination. They were diagnosed as “right sacral bone tumor” and biopsy.
