Or can I/should i seek treatment?
Do you have any discomfort, itching or discharge from that ear? If the answer is No then you are fine. Stop looking for problems where there arent any.
thank you. i looked in my ears because they are itchy, but just wanted some confirmation, because it looked like mold.
If they are itchy then yes it could be mould but it could be other things as well. See a professional to get some medication.
If you're at all concerned see your gp. We are not trained professionals. All the best.
