Can poison ivy spread into the ear?

Yes, poison ivy can spread into the ear if the urushiol oil from the plant comes into contact with the skin in that area. The oil can cause an allergic reaction, leading to a rash and irritation. It's important to wash any exposed skin promptly with soap and water to minimize the risk of spreading the oil to other areas, including the ear. If irritation occurs, it’s advisable to consult a healthcare professional for appropriate treatment.
