Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain foul smelling discharge from ear with a previous history of traumatic
injury to the ear and loss of hearing that can be due to perforation of the ear drum can e due to infection in ear and the discharge seems to be pus..
I would suggest you to consult an ENT expert and get evaluated and a thorough clinical evaluation can help in diagnosis and he can also advise Otoscopy..
In case of infection he can advise you
oral antibiotics like
Augmentin or Cephelexin, anti-inflammatory painkillers like Advil, decongestants nasal sprays containing
Xylometazoline, antibiotic ear drops like
Gentamycin ..
The pus discharge can be drained out manually by syringing to resolve the infection faster..
Hope this information helps..
Thanks and regards.
