Bunions are caused by the bursa at the base of the big toe becoming inflamed and swollen, so it pushes against the skin.

Bunions can cause pain in your foot and lower leg because they “put pressure on other structures in your foot.”

This is because bunions can cause pain in your foot and lower leg because they put pressure on other structures in your foot. This can lead to chronic pain, making walking, running, or even standing up for long periods of time very difficult. You may also experience burning or numbness or tingling sensations. Sometimes people with bunions will have a limp due to their discomfort with walking.
