There is a CCC right near Northern Virgina/DC : the Lombardi Cancer Center at Georgetown Hospital - right across the Key Bridge and up a few blocks. In case you want something closer than John Hopkins in Baltimore.
there were lots of head and neck patients in the radiation waiting room when I was being treated there. Plus I am planning on having my recurrence surgery there. I went over a year after finishing treatment without needing surgery and even now with stage IV coming back, they are not talking 80% of my tongue. I echo the advice from the other posters to get a CCC workup.
Good luck.
