Is putting olive oil in my ear supposed to hurt?

My family doctor said to put olive oil In my ears before I go to bed and after I wake up. In order to clean the wax out of my ears.

After on the 20th she will flush my ears of the remaining wax.

Am I applying wrong? Or is the olive oil rancid?

I just stick my finger in the olive oil spout and tip it until a drop goes on my finger, and repeat for both ears.

What do you suggest I do?
