Wow yo did so much with your ears .
I suggest you not to do all this in future.
You should consult an ENT specialist
and get examined so that proper treatment can be done .
The blockage colud be because of the cotton or sinus infection
but without examination its difficult to say.
If you try to clean your ears like this there are high chances that yo may damage the ear drum and then it will become a long term problem and it may be that you may require surgery later .
