6+ months abdominal pain - What do these test results reveal?

[dsaj]

Recently completed a round of testing to perhaps explain why I have been in significant abdominal pain for a long time.  The latest bout is 6+ months.  I can't make out from these results what may be going on and I do intend to see a urologist but that visit is a few weeks away, so in the meantime I am wondering if this seems familiar to anyone.
Problem areas of results:
Blood, UA:  Large
RBC, UA:  10-50 hpf (so red blood cells in urine)
Bacteria:  Rare
Squam Epithel, UA:  Moderate
Enlarged Lymph Nodes
CT scan noted no significant issues beyond the somewhat enlarged lymph nodes.
Physician's note said he suspected a viral abdominal infection. (Could that be possible at the six month mark?)

Should I be concerned?

Hi, there is no reason there to suspect lymphoma.

Where are the enlarged nodes located? They are apparently *reactive* to something going on inside.
