Chilblains can often be mistaken for other conditions that cause inflammation of the skin. These conditions may include allergic reactions, contact dermatitis, and insect bites.
Allergic reactions are caused by an overreaction of the immune system to an allergen, which can be anything from a food, pet, pollen, or medicine. Symptoms of an allergic reaction include redness, swelling, itching, and hives.
Contact dermatitis occurs when the skin comes in contact with a substance the body perceives as a threat, such as a chemical, plant, or metal. Symptoms of contact dermatitis include redness, swelling, itching, and blistering.
Insect bites are caused by the venom of certain insects. Symptoms of insect bites include redness, swelling, itching, and hives.
Chilblains are caused by exposure to cold temperatures and are generally found on the feet, hands, or ears. Symptoms of chilblains include redness, swelling, itching, and blisters. If left untreated, these symptoms can become more severe and cause pain, ulceration, and even infection.
If you experience any of the symptoms listed above, it is important to seek medical attention to rule out any other potential causes. A medical professional can help determine whether the cause is an allergic reaction, contact dermatitis, an insect bite, or chilblains.
