I had a bunion on my right foot for over 20 years. It became more painful over the years. Plastic mountaineering boots were the worst, even after blowing them out at a ski shop.
I had surgery for it 3 years ago, Thank God the body can't remember pain, a week or so of pure agony, then a month or so on cructhes ( some how I forgot to bring them on our trip to Hawaii.)
Today, I think the surgery was one of the best decisions I've made. No more pain and foot wear that lasts more than 3 months. Good luck.
