I have this problem too, let me explain why I struggle to resolve it.....
I'll get a muffled, blocked sound in my ear. I'll see the doctor, he'll tell me to 'put warm olive oil into the ear to soften the wax.'
I go home and do that, and the oil expands the wax and causes my ear to become inflamed and extremely painful. I will then go back to the doctor who will try and syringe it, which will be unsuccessful, because my ear is too inflamed to squirt water in at high pressure.
I then wait for the inflammation to die down, return to the doctor, who will then tell me to put warm olive oil into the ear to soften the wax before he/she can syringe it.
It's a common pattern that I see all the time with doctor's. A circle that I don't know how to break.
