Rheumatologist - Brussels

Dear All,

can you recommend a good rheumatologist in the Brussels area or nearby? I've been suffering from joint stiffness and backaches. My GP has given me anti-inflammatory medications which seem to be working as for now, but I'm afraid I may need a specialist in the future. Thanks a lot in advance. (By the way, I have an impression that St. Luc is fully booked for months ahead, which is too bad as it's my nearest one).
