See this blog about bunions and shoes to see of you can find anything for your feet www.callashoes.com before you go for the op. I've thought about it too but don't have the luxury of being off my feet during recovery as I have two small children.
Look at why you've got them before you decide to go ahead with surgery. Are they because you over pronate when you walk (your foot turns over towards your big toe slightly)? Or are they as a result of poor fitting shoes? I over pronate and wish I'd not bothered having it done. It was quite sore when it was done, but I had post op pain for months and months afterwards. Turns out it was because my four was just going back to the original shape pre-op because the way I walk was forcing it back. They didn't tell me what had caused it initially.
My issue is the same as blue... My feet over pronate so no point in getting the bunion surgery done. The bunions kind of form to stop your feet rolling inwards! I always wondered why I stopped walking like a duck and it's because my bunions had got so big ha ha!
