Numbness in a bunion can be caused by compression of the nerves in the area. This compression can be caused by the bony protrusion of the bunion itself, as well as inflammation and swelling in the surrounding tissue. In some cases, the numbness may be temporary and resolve on its own with rest and the use of over-the-counter pain relievers. In other cases, the numbness may be chronic and require more aggressive treatment, such as physical therapy or even surgery, to alleviate the symptoms. If you are experiencing numbness in your bunion, it is best to consult with a podiatrist or orthopedic surgeon for a proper diagnosis and treatment plan.
