A bunion is a bony bump that forms at the joint at the base of your big toe. This deformity can sometimes press on nearby nerves, causing numbness or tingling in the big toe.

As the big toe angles toward the second toe, the underlying bone structure shifts. This can compress the medial plantar nerve, which runs along the inside of your foot and supplies sensation to your big toe.
