The therapeutic effect of small needle knife on heel pain is relatively accurate, because there are many clinical causes of heel pain, including lumbar intervertebral disc herniation, injury to the infrapatellar fat pad, heel bone spurs, subacromial bursitis, thinning of the fat pad, and heel osteoarthritis, as well as injury to the erector spinae muscle, the lumbar square muscle injury, and other soft tissue force balance imbalance. However, regardless of the cause of heel pain, as long as the diagnosis is clear, the treatment of most heel pain can often play a very good or even immediate clinical effect. Therefore, the causes of heel pain should be actively analyzed in the clinic, and targeted treatment can have good clinical efficacy. However, there are individual patients, clinical repeated treatment effect is poor, will also take the local heel bone decompression and other auxiliary treatment.
