Pain in the medial aspect of the heel root bone is mainly considered in the following two aspects: 1. Local periostitis or fasciitis. It is mainly due to cold or excessive activity, poor local blood supply and anaerobic metabolism, resulting in aseptic inflammation caused by the aggregation of metabolic products, and imaging examination is not able to find obvious abnormalities, which can be recovered by resting with hot compresses, reducing activity, and topical application of Fotarine ointment for 1-2 weeks. 2, ankle canal syndrome. The tibial nerve enters the ankle canal and is compressed by the root branch of the tibial nerve, resulting in pain and numbness in the medial aspect of the heel bone, which can also be manifested as a single pain.
