Swollen feet, ankles, and legs are a common condition, especially in elderly people. There are many possible causes of swollen feet, although a red or warm foot may indicate an infection.
Causes of Swelling
Swollen feet can be caused by pregnancy, menstrual periods, prolonged standing, ageing, injury, blood clots, varicose veins, sunburn, certain medications, or insect bites.
Causes of Pink Skin
Pink or red skin may indicate an infection. Other signs of an infection include warm skin, pus, swelling, and pain.
Exercise and eat a low-salt diet. Elevate your legs while resting, and consider wearing support stockings. If you have a wound on your foot, wash it daily with soap and water and apply a disinfectant two to three times a day.
If you feel short of breath or notice chest pressure, call 911. If you have a fever and your foot is red and warm, seek immediate medical attention.
Don't sit for long periods of time. Stretch and walk every hour or so during flights and long car drives. Don't wear tight clothing, and lose weight if necessary. Prevent infections by keeping your hands clean, not picking at wounds, and washing cuts with soap and water.
Your doctor may perform blood tests, chest X-rays, urinalysis, or ECG tests.
