Well, I had pain and a throbbing up in an empty socket in my upper jaw (where a tooth with an Amalgam filling cracked, and it had to be extracted). I think a cavitation up in the bone can linger quite a while. I noticed reactions in that section and a bit of swelling around the eye-socket for about a month, but after using vit k2, the infection symptoms slowly ebbed and then went away.
I thought I'd mention it in case that could help you, it's a nutrient indicated in tooth and bone health.
