Confused

Hi, I hat a CT scan on 19th December, Friday I received a call, it all just seemed such a blur now . Back last year I was diagnosed with Rheumatoid Arthritis, after many blood tests one of my markers would not lessen , so a CT with colourant was prescribed, that was the 19. Any way the outcome was suspect swollen nodes in my neck, which I can't feel , I just feel lost , I don't want to tell anyone close to me yet, as it's just circumspect . Any ideas ?
