When I was younger, I broke the bones in my foot around the middle part, where they all join. My doctor put a cast on it and a few weeks later, I was back on my way. My foot has always hurt since then but x-rays show that my foot is fine. Could it be arthritis since it's getting worse?
If you did break the tarsometatarsal joints several years ago and the bones didn't heal back in proper alignment, it's entirely possible that you are developing arthritis in that area. This is one reason why doctors recommend surgery for this type of injury, even if the displacement or bone movement is minimal.
