Frostbite is an injury resulting from freezing of the tissues in the body. The hands and feet are most commonly affected by frostbite, but ears may also be affected by frostbite.
The areas of the body affected by frostbite feel cold and firm. Burning, tingling, stinging, or numbing sensations may be present.When the affected body part is rewarmed, a throbbing or burning pain may result. Frostbite, like burns, is classified according to the degree of tissue injury. Minor injuries result in swelling, redness, loss of sensation, and white plaques on the skin. More severe lesions have blisters that may become filled with blood.
You can treat with nonsteroidal anti-inflammatories such as Ibuprofen if it is minor or if you are concerned see your doctor. In mild cases, full recovery can be expected with early treatment. Severe cases of frostbite can result in infection, or gangrene.

Prevention of Frostbite
Since you have had an injury to your skin on your ear previously, you are more susceptible to burns and frostbite, as you have new tender skin tissue. Before going outside in extremely cold temperature, apply skin moisturizer to the face, hands, and any other body part that may be exposed to the cold. Dress warmly, wear dry clothing, and stay out of the wind. Wear a face mask for extra protection, and ear protection. Wear heavy mittens instead of gloves in freezing cold weather. When the fingers are together in a mitten, their collective body heat keeps the hand warm.
It is -6 here today, -19 with wind chill factored in. Brrr......cover up this winter, and remember to protect your ears in the summer too with sunscreen. Hope your on the mend soon!

Yes is sounds like mild frost bite. I would have a Dr. look at it to determine the severity.
