At wits end with the pain (day 11)

11 days ago I got 2 teeth extracted from my lower jaw. I did everything I was supposed to do and it still hurts in the left side, the right side is completely fine. I called the hospital where got my teeth removed and they told me that it’s normal and just to take ibuprofen en paracetamol at the same time. Why has the pain not gone away ? Why is the hole still open. It hurts every few hours and I can’t do this anymore.
