Is swelling and pain normal after an impression is taken for a final setting of a dental implant?

I'm in the process of getting a dental implant. The piece was put in that needed to heal and healed properly with no complications. Today I got an impression taken to finish the procedure. So she unscrewed the bit on top and took an impression. All was well no pain seemingly no problems. However it's been about 8 hours and im having a lot of swelling and pain in the area and into my jaw. Is this normal and will go down eventually or would you say there is an infection showing up already?
