Foot problems are common problems, especially foot pain is very common, can be divided into forefoot pain, such as foot surface pain, toe pain, foot pain, medial and lateral foot pain, etc., midfoot pain, such as dorsal foot pain, arch pain, sole pain Guinea or lateral pain, hindfoot pain, such as heel pain, ankle pain, ankle bone pain, etc., the correct distinction between these pains is very important for a clear diagnosis, so it is necessary to carefully investigate the body, not to ignore every small foot bone, every ligament, every joint crevice, etc. The structure of the foot is complex and its function is more difficult to understand, so foot diseases are very easy to misdiagnose and miss, resulting in delayed treatment or incorrect treatment. It is recommended that if a patient has a foot problem and the treatment by a general orthopedic surgeon is not effective, he or she can seek consultation with a foot and ankle surgeon or even seek consultation with multiple foot and ankle surgeons in order to make a clear diagnosis and prevent delayed treatment.
