It can be difficult to know what's going on when something's wrong
with your body. If your feet are swollen, does it mean you're having an
allergic reaction? Did you just drink too much water? Have you spent too
much time on your feet? Or could it be a sign of something more
serious, like kidney issues?Some signs of kidney problems are
obvious, like blood in the urine; others are much more subtle and can be
signs of other problems, too. But taken together, these might add up to
a trip to the doctor to get your kidneys checked.
