Had a temporary crown put in, few hours after the procedure, my ears feel like they're popping?

I had a root canal done end of Oct.2016, and today Nov.10 had a temp crown put in, few hours after the procedure, my ears feel like they're popping, and right under my ear and close to my jawline when I lightly put pressure on either it feels like there are pop rocks in my cheek and ear (wondering from the shot?)..the pain is on a scale of 5-7, my face is swollen, and close to the molar there is a hole in my gums..suggestions?
