Gray earwax
If you notice gray earwax in your ear canal, there are two possible explanations. It may be due to ambient dust from pollution, especially in large cities.
Earwax with a touch of blood
If a cotton swab is placed in the ear and bloody earwax comes out, it means there is an ear hemorrhage, that is, blood leaking from the ear. The causes can be various, such as over-cleaning, a violent blow, an infection such as an ear infection, or even the presence of a tumor. In any case, immediate consultation with a doctor is recommended.
