Bunions are bony bumps that grow on the joint at the base of your big toe. This protruding bone can change the shape of your foot and cause your big toe to tilt toward the other toes. Over time, your toes may begin to overlap and rub together, causing corns, calluses, bursitis, or hammertoe. You may have trouble bending your foot or fitting it into shoes.
For some people, wearing flat shoes with wide toe boxes instead of high heels is enough to prevent bunions or keep them from growing. But people with a family history of bunions, or certain medical conditions like rheumatoid arthritis, may develop bunions no matter what type of shoes they wear.
Bunion surgery may be recommended if you experience severe foot pain when walking, or your foot swelling cannot be relieved with medication.
