The restricted range of movement from an arthritic big toe.

What symptoms might I get with hallux rigidus?
Like osteoarthritis in other joints there are a spectrum of presentations. These range from a painless bony "growth" on the top aspect of the big toe
to discomfort in particular positions of the big toe (especially in higher heels or during "push off" in running when the toe becomes maximally extended). Eventually pain may be present throughout most weight bearing activities or even be present regardless of whether a patient is weight bearing on the foot or not. As with other arthritic conditions the progression of hallux rigidus is unpredictable and may not necessarily occur.
