There is blood on my ear rings when I take them out my ear is also red, swollen and warm what should I do?

Go nickel free. this could be due to a condition known as contact dermatitis. You may have become allergic to a component of your earrings. Nickel is the most common. Sometimes cobalt. Try switching earrings to nickel free ones and see if it helps. if it continues you should see your doctor, if it’s not infected, may recommend a dermatologist or an allergist that tests for Contact dermatitis chemicals.
