Welcome to HealthcareMagic forum.
It seems you have traumatized your auditory canal. In such cases the most common injuries are located over the tympanic membrane (ear drum) and such injuries do heal well if you been healthy.
However as you report hearing impairment
, it warrants a clinical examination by a competent ENT specialist
I understand a visit to a doctor is not what you wish, but perhaps you may visit a free clinic where a doctor can look into your ear and confirm the type and severity of injury
. We can then plan a type of treatment then.
Hope this answers your query.
