Pain!

I just got my root canal redone 3 days ago. My mouth is in serious pain on the left side/jaw. I have never been in so much pain I broke down. When the dentist did my tooth he did poke a little far at one point and I looked up saying it could be inflammation. I just took ibuprofen but I have pain killers am I able to mix them together? I have a follow up with the dentist again but that’s not for another two weeks and I just don’t know why it hurts so bad!
