Why does my gums near my bottom second molar tooth hurt so badly?

                        The gums near the second molar tooth to my right on the bottom hurts so badly.  It's been aching for 2 days and today, I have a terrible pain.  My ears hurts and everytime I swallow, it hurts so badly.  I'm a college student and I have 4 exams coming up next week and on top of that, a pre-nursing exam I'm taking the week after.  I don't know if it's wisdom tooth, but I can';t afford to go to the dentist.
Is it wisdom teeth? I've been taking advil, but I heard it's not safe to take it everyday.
What can I do? Does the pain go away?
