Bunions are a progressive deformity. This means that they will typically get worse over time. It is true that the foot becomes more unstable as the bunion gets bigger. This means that it will often get worse at faster rate over the years. Having said that, it is unpredictable as to just how fast the bunion will become intolerable. As a general rule, bunions are a surgical problem. However, you should only have your bunion surgically removed if it is painful or interfering with the activities you enjoy. Once you start to picture what your life would be like if you had no bunion pain, that it is when it makes sense to talk with your foot surgeon about fixing the problem.
