I think you are right. I have had similar experiences. I believe I have an active infection in my jaw from an extracted wisdom tooth now. The tooth was taken out about a year ago and there is still pain. Zapping seems to make me worse. I don't know how to treat this active infection in my jaw.
The dentist used a vasoconstrictor during the extraction and I believe it caused these problems. It looks like I will have to go back for surgery to clean this out. I am reluctant to use Antibiotics though. Could you possibly describe your cavitation surgery and how it was done.
