Bunions are bony protuberances that develop at the base of the big toe, causing the big toe to angle towards the second toe. The bunion itself is the bony prominence that forms at the base of the big toe. The skin over the bunion may be red and sore, and the area may be swollen. In some cases, the bunion can also cause calluses or corns to form on the toes or foot. It's important to consult a podiatrist or orthopedic surgeon for a proper diagnosis and treatment plan, if you suspect you have a bunion. They will be able to provide you with pictures or x-rays of your foot to give you a better understanding of the condition.
