enlarged lymph node near liver

I had an extreme case of shingles with post herpatic neuralgia which lasted almost one year.  I still have pain but it is now tolerable without pain meds.  I noticed pain in my left side front below where the shingles pain has been and decided to tell my doctor. I actually feel a bump at the site the size of an elongated golf ball. He had me get an abdominal/pelvic CT.  It showed nothing at the site however it showed an enlarged lymph node between my stomach and my liver on the other side. He suggest we get another scan in 3 months to compare.  I'm worried.  Should we wait 3 months?  I read in the newspaper that DR. GOTT said that 50% of people who get shingles already have cancer somewhere else in their bodies. Is this true? Could there be any correlation between my shingles and this enlarged lymph node? The radiologist told my PCP we should have a sonogram but my PCP says they don't show anything, he would rather wait 3 months and get another scan.  Do you agree?

That 50% number seems high to me.  Shingles can occur due to an immune deficiency, and it may occur unrelated to any cancer in the body.  

A periodic imaging scan is a reasonable approach to ensure the lymph node does not enlarge.  I agree with an ultrasound to further evaluate the liver and gallbladder for any suspicious lesions that may not be seen on the CT.

Obtaining another opinion can be considered if there is question as to the diagnostic course.
