Should I go to the dentist?

I went to the dentist for the second time in two weeks for pain in a tooth on my lower left side when I drank cold things. She said I needed to have another filling and I got others filled that same day. But it's been 4 days and I now have pain when I chew in that tooth that got filled. I'm trying to decide if I should go back now or of I should wait. If I wait I won't be able to go until I get back from vacation in mid June or risk that it just needs time and go back soon. But though my teeth are sensitive I've never felt this pain so much longer after getting it filled.
