To understand the pain due to the hallux valgus it must be remembered that the pain is not often in the bunion (medial prominence) but in other parts of the foot. This is because the appearance of a hallux valgus normally produces a dysfunction of the foot and an overall change in its support. This situation of disequilibrium creates a sequence of very characteristic changes in the foot.
The consulting symptoms are mainly pain and deformity. However, hallux valgus causes symptoms in three specific forms:
Pain in the medial prominence which appears due to the bones of the foot deviating. This pain is due to pressure and the shoes rubbing.
Pain in the sole of the foot (metatarsalgia) due to changes in the normal function of the foot support, which causes excessive pressure below the metatarsals. It can be very crippling.
Deformity of the adjacent toes. Due to the deviation of the big toe, there is compression and displacement of the adjacent toes that are also deformed (claw toes, hammer toes, etc.).
As such the symptoms of hallux valgus are due to two factors:
The deformity of the big toe itself and the other toes (generally due to the pressure and rubbing over the prominent areas).
The change in the support resulting from it (pain in the sole of the foot below head of the metatarsals or metatarsalgia).
Signs of the Bunion
Appearance of a lump in the middle part of the foot (bunion).
Lateral deviation of the big toe (hallux valgus) and smaller toes.
Deformity of the small toes (claw or hammer toes).
Calluses on the sole of the foot (hyperkeratosis).
