The problem is that you have a misconception about what is going on here, I believe.
The problem is from the drum inward, not in the external canal.
You can not clear this out because it likely represents fluid behind the drum, or a thing coating of liquefied rash that has coated the drum.
Or, from inflammation , it already represents nerve damage in the hearing apparatus because of the amount of time gone by.
The ENT visit is not an optional thing at this point, but a mandatory, if not emergency visit as inflammation can cause permanent hearing loss as can fluid in the ear that is left unattended.
In some cases a medication such as sudafed will dry up the Eustachian tube and actually prevent drainage from the middle ear, making the problem worse.
Therefore, I would see an ENT tomorrow, if not an emergency room doctor tonight.
