I am following this thread because we are going through this as well. The oral surgeon has had my husband on antibiotics for almost eight months. He went through 20 HBO dives before he had two teeth removed, and another 20 afterward. The incision wasn't healing, he was still in pain, and would still swell up. The surgeon went in and scraped dead bone and tissue this past week and sent the sample to a lab. I have read through many posts about this condition to try to prepare myself for what could be next.I am also scared. We will find out more this week.
