There is no abnormal tissue or tumor growth in bunions, the protruding bump comprises mostly of the head of the first metatarsal bone.
Causes of Bunions
The exact cause of bunions is still unknown. Using improper footwear can be one of the cause: a study shows that people in countries that regularly wear shoes such as in western countries have higher incidence of bunions. On the other hand, people in Asian countries mostly use sandals and were found to be less prone to develop bunions. This could also be the main cause of hereditary bunions due to decades of wearing shoes. The supporting structures of the feet seem to weaken, leading to this foot condition.
Women are particularly prone to bunions due to chronic use of ill-fitting shoes like tight pointy high heeled shoes. People who have leg length discrepancies, previous foot injuries, and arthritis can form bunions.
Signs and Symptoms
