you said you are having discharge since childhood , then i expect you have shown to ENT specialist
If you have discharge at young age without any other medical illness then there are more chances that you have a perforation in both of your ear drums .
In that case such a long perforation never heals on its own ,you will have to consult and get it operated.Before that you can get done
otoscopy (viewing through the ear canal
)to confirm the disease / perforation this can be done by ENT specialist.
Pure tone audiometery (hearing test ) to know the extent of hearing loss
so that the surgery can be planned accordingly
mastoids / HRCT temporal bone
---which is to be done will be decided by your doctor.
Dont just avoid treatment as long term discharge will lead to hearing loss.
Till then AVOID WATER ENTERING YOUR EARS
