It lies deep to the deep aponeurosis and flexor retinaculum, differentiating it from the accessory soleus muscle.radsource.us/accessory-muscles-of-the-ankle/Some persons are born with accessory muscles. These variations from the norm can cause more harm than good. Those muscles are not necessarily helpful, but it is a given that they do occupy space within the foot. Similar to hypertrophy of the muscles in the medial ankle region, this can compress the tibial nerve possibly resulting in chronic pain.www.physio-pedia.com/Tarsal_Tunnel_syndrome
