The body speaks volumes about what ails it -- from obvious warnings like a fever that accompanies an infection to subtle clues like losing hair on the toes, which can be an early sign of vascular disease.
Some signs that seem alarming may actually be harmless
But some that seem minor can warn of a serious disorder
Other signs seem to make no logical biological sense
The problem is that many of us don't recognize the warnings
Before you race off to the doctor for every lump or discoloration, remember that anomalies you've had for years are more likely to be a harmless part of your genetic makeup
Signs and symptoms that are unusual for you, or painful or debilitating, are more likely to be significant
many doctors and nurses alike say that patients, too, should be vigilant for anything new or unusual about their own bodies
With major changes to the nation's health-care system looming, it may be more important than ever for people to keep track of their own physical health
