Hallux valgus is a common foot condition, known as bunion more commonly; it does run in families. You don't have to be extremely worried about it. It is not something which is going to cripple you but it may cause trouble in the future like callus formation, pain, deformity. What you can do at present is to avoid wearing tight fitting shoes, wear shoes with open or wide toe boxes. If you have flat feet, use medial arch supports to avoid pronation of your feet. These inserts are available over the counter, there are also spacers available, which you can use between the great toe and the second toe. If the deformity worsens, or you are symptomatic, then see a foot specialist. The other option is get surgical correction. I don't think you need it right now.
