Hello and welcome to HCM,
Discharge from ears which has foul odor is suggestive of infection.
Small ear canals is not the likely cause for pain and discharge.
Crusting can occur due to accumulation and drying of discharge outside the opening of ear canals.
The symptoms of pain and foul smelling discharge is suggestive of infection of middle ear and probable extension into the adjoining bone.
Since, the middle ear is in close proximity to brain, thus, it is essential to detect the infection and treat it timely.
Thus, it is essential to get the ear examined by an experienced
ENT specialist to detect infection or any other lesion.
In case of infection, appropriate antibiotics should be taken.
Thanks and take care
