I don't have any home remedies; I can just say... reading what you've been feeling, I can just about feel the pain myself.
Please post as soon as you either speak with or see your doctor. Likely, what you learn will also help others who go through similar.
I honestly haven't any idea what your doc might suggest. I know that when I've nerve pain (in my face and dental related), ice packs help. Huge caveat: Mine isn't related to extraction(s).
That you're seeing bone, it suggests to me, you've made the best decisions so far. I hope they're able to see you earlier than in the afternoon. The less suffering you feel, the better.
