I am still in the stage of finding out what is really wrong with me, but I thought I would chime in with my 2 cents. My titers came back extremely high, in fact over twice where yours are at, so I understand the anxiety it can cause. I have learned through research and help on this forum that most General Practitioners don't have a clue as to what to do with the numbers or the patients. I am not putting down your doctor, but I have a great regular doctor who is a complete idiot when it came to CEBV.
I have an appointment with a Rheumatologist who stated he has a lot of experience dealing with CEBV. In my opinion I would consult a Rheumatologist, but I would also mention my results to my Hematologist.
PlateletGal seems to have a ton of information about all of this, and she gave me some great links to information that really helped. Here is the link to that post:

I would just copy the links for you but she had some useful information along with the links.
