There are two good reasons to postpone surgical "repair" as long as possible: (1) From all I have read, you may loose some mobility in the joint; (2) It may re-develop since the cause is biomechanical. I went through a similar period years ago, but it seems to have stabilized and does not hurt. That's when I started to use insoles with arch support in various shoes (now I have them in my cycling shoes as well, the Specialized BG footbeds, 3/4 Birkenstock insoles in my loafers...).
