Thank you for posting your query on DoctorSpring.com. I can understand your problem.
Your friend is suffering from recurrent ear infection. He is suffering from left sided hearing loss for 3 months and now right sided also.he had ear discharge also. He is started on amoxicillin.
Most likely he is has eustachean tube dysfunction ( tube connecting ear and nose) causing recurrent ear infection. He may also have perforation in ear drum (which is the membrane that separates the outer ear from the inner ear).
He needs examination by ENT specialist again. I would suggest that he get an audiogram and tympanometry to check type and severity of hearing loss. Other investigations can be decided based on result of these.
We can add tab. Levocetrizine 5 mg one at night for 3 weeks. Ear drops can be decided based on ear examination finding.
Hope this helps
