Swollen ankles and cold feet may reveal hidden heart trouble
Your legs can tell you if your heart needs help because the heart pumps blood to your whole body, including your legs.
If your ankles or feet look puffy, it might mean your heart is not pumping very well and fluid is building up.
Pain in your legs when you walk that goes away when you rest could mean your blood vessels are too narrow.
Cold feet, numb legs, or skin that looks pale or blue can also be clues.
Cuts or sores on your feet that take a long time to heal are another warning sign.
If one leg suddenly swells or hurts, you should see a doctor right away.
But swelling does not always mean heart trouble, since it can happen from sitting too long or from kidney and liver problems.
If swelling gets worse and you feel very tired, short of breath, or gain weight quickly, that is a sign to get help fast.
People with diabetes or high blood pressure should watch their legs carefully.
When something feels wrong, always ask a doctor.
Doctor lists 7 leg signs that may reveal hidden heart trouble, including swelling, pain, cold feet, numbness, and slow-healing wounds.
Leg pain or cramping while walking that eases with rest may indicate peripheral artery disease.
Swelling around the ankles and feet can signal heart inefficiency, vein pressure, or fluid retention, but may also stem from kidney or liver problems, medications, or prolonged sitting.
Recurring swelling that worsens, disrupts daily life, or comes with breathlessness, tiredness, rapid weight gain, or difficulty lying flat requires urgent medical attention.
People with diabetes, high blood pressure, high cholesterol, obesity, a history of smoking, or a family history should closely monitor changes in their legs.
