I may have a bunion! Help!?

See a foot doctor. A foot doctor could properly examine and determine the measures to either correct the bunion if it is there, or to advise you on avoiding its progression.
Bunion. See your podiatrist for an evaluation and discussion on bunion formation and treatment.
Have it evaluated. A bunion is a progressive disorder that is often described as a bump on the side of the big toe joint which may become painful. The visible bump actually reflects changes in the framework of that joint and possibly adjacent joints. In later stages, the big toe may lean towards the second toe which throws the bones out of alignment – producing the bunion’s “bump” which may lead to pain.
