Most of us don’t realize how much we use our big toe. We tend to take it for granted, unless a problem develops. One problem that afflicts the big toe is called hallux rigidus, a condition where movement of the toe is restricted to varying degrees. This disorder can be very troubling and even disabling, since we use the all-important big toe whenever we walk, stoop down, climb up, or even stand. If you have pain and/or stiffness in your big toe, you may have this condition.
