Hi Dr Rynne, I Been Having This Frequent Occurrences Of

Hi Dr Rynne, I been having this frequent occurrences of my inner ears being itchy. This has been going on for years. There are no ear wax and been clear by GP. I also have this frequent blockage of both my ears, and it is affecting my hearing. I have to repeatedly "blow" my ears to make myself feel better. It is worse when it is too cold or hot environment. This problem is causing me to lose focus and the people around is bothered by my frequent blowing sound. I have been to many different doctors, it does not seem to help. Doctor prescribe anti-itch medicine, sinus spray and ear drop to clean wax. But there is no wax!

Please advise.
PS: Will polydexa helps?
