Thanks for writing to H.C.M. for your query.
I have gone through your query regarding whitish stuff came out of ear canal
, and your doctor said that your ear is cleaned . It meanes the whitish stuff may be fungus.
You are suspecting for herpitic ulcer in ear canal but it is unlikely because you have no pain and burning which is characteristic of herpitic infections.
For your throat infection
you can take any broad spectrum antibiotic, decongestant syrup and warm saline gargling.
