Severe pain after root canal, is there ANYTHING I can do about this?

I just can't handle this pain anymore, after 5 days of constant, literally non-stop severe toothache I had to get a root canal today.

Contrary to what I've read online, it has not relieved the pain, and I have severe pain throughout the right side of my gums, all up the side of my face, and a severe headache. My dentist wouldn't give me anything, just said take Advil. I've been taking that for days on end every 5 hours or so, it doesn't do a thing, even with Tylenol.

The root canal isn't even finished. He said 90% of it is finished, but I have to go in next week to get it finished. I can't handle this pain until then.

Is there ANYTHING I can do about this? I've considered going to the hospital to get antibiotics or some sort of stronger pain reliever, should I do that? I can't sleep and can barely eat.
Update: Thank you for the information so far. Joyce, I'm honestly telling the truth, he didn't provide me with any antibiotics or pain killers, despite the fact that it was quite a severe infection. I did ask them, they said take a Advil and Tylenol combination, which doesn't do much for me. I've used this... show more Thank you for the information so far.

I've used this dentist for a while and they seem quite professional, but I'm guessing very lax on giving out antibiotics.
