Post tooth extraction?

I had a tooth pulled the other day and haven't really felt well since and the roof of my mouth and my gums hurt and the pain medicine isn't helping that. I don't see any harm in using a liquid numbing on my gums and roof of my mouth as there's a flap covering the extraction site and I'm not gonna put it right in the whole just up on the gums and roof of my mouth to help it feel better but I know it's gonna drip down around the whole. I've been keeping it super clean and have no bleeding or anything so figured it would be ok. Just wondering if anyone was ever told not to use something like orajel or I got a bottle of liquid numbing stuff that I use.
