Thank you all for your replies! I really, really appreciate your advice.

I called the periodontist's office today and both the dr. and his assistant are out. The dr. will be back next Monday when I have my appt. The assistant will be back tomorrow and I will call back tomorrow to talk to her. Also, I called Johns Hopkins where they did the lab work. It was read on 5/16. They will mail the results to me (they can't fax them) and because I asked for a quick turn around, I will get them this week. The person in the medical records office was so kind and helpful! I really wished I had gone to the ENT at Georgetown for the biopsy though. I think I would have heard back much sooner.

It really has been torture waiting. I'm at work and in near tears. Thanks again to everyone who responded to me! You really have a very special community here! Best wishes.
