Common Causes â¢ â¢ â¢ â¢ â¢ â¢ â¢ â¢ â¢ â¢ â¢ â¢ â¢. Arch pain is most often caused by strained ligaments or tendons. If the pain is toward the distal portion of the arch (closer to the big toe), it may be related to the attachment of the plantar fascia, which is a major ligament supporting the arch.
Muscles in the foot also help support the medial longitudinal arch. 1  These include: 2  flexor hallucis longus. 3  flexor digitorum longus. 4  abductor hallucis. 5  flexor digitorum brevis muscles. 6  tibialis posterior, which is the most important muscle in the maintenance of the arch as damage to its tendon results in collapse of the arch. The tibialis posterior and anterior muscles help to raise the medial border of the arch whilst the flexor hallucis longus acts as a bowstring.
