A bunion is a large bump on the side of the foot that develops at the base of the big toe when the toe deviates inward. It is very common for a bunion to be swollen and inflamed, leading to foot pain. Most commonly affected are women and older adults, although anyone can develop a bunion. If left untreated the joint may enlarge, becoming stiff and painful. This can lead to problems with getting shoes to fit as well as difficulty walking. Physical Therapists can help individuals with bunions by improving the angle of the big toe, increasing muscle strength and walking mechanics, as well as reducing discomfort.
