I think my Eustachain tubes are blocked again after using wax softer as I have pus. Dizziness. And blocked ears how do I unblock. Doctor won't do noth?

Reason? Can you explain why the "Doctor won't do noth?" Sometimes we feel that our ears or Eustachian tubes are blocked even after we believe they've been adequately treated with medication and then, believe we need another round of antibiotics or antihistamines, or whatever. But in reality they've been treated but it takes a little time for things to go back to normal. Is that possible?
