Bunions are a deformity of the great toe joint in which the big toe starts to point to the second toe. Over time, the bones in the forefoot change and a large bump can develop on the side of your foot. Symptoms of a bunion include pain in the effected area, swelling, inflammation, numbness, pain under the joint of the second toe joint, secondary to the big toe joint not bearing excessive weight.
The bones underneath the big toe joint can also become inflamed, making walking quite difficult. Bunions are typically hereditary in nature. You're typically born with a foot imbalance that makes you more prone to developing a bunion. Shoe gear typically does not cause a bunion deformity, but it can exacerbate the development and cause pain as a result of the irritation.
