large spleen worried about lymphoma

I had been having pain in my RUQ for about 2 months, went for a physical in June with complete blood work.  Blood work showed mildly elevated liver enzymes.  Was sent for ab u/s which showed fatty liver, spleen upper limits of normal and an area 'of increased density on the kidney'.  The radiologist recommended a ct scan to rule out a mass.  The ct scan was done and was normal except mild fat infiltration of liver,  a large, bulky spleen, that was still within normal limits.  No abnormalities were identified on the kidney.  I still have the pain, which isn't bad, just achy, never have to take anything for it.
On top of all this I have had sinus congestion and a dry cough for over a month.  I had a chest xray which was normal.  I now have tenderness over the left ribs almost feels like a bruise.  I am tired but functioning.  I don't get much sleep at night because of anxiety and nasal congestion.  Other than that I don't have any swollen glands that I can palpate.  I am worried about lymphoma.  My question is would the blood work done in June have shown any abnormalities if this was lymphoma. Can one have lymphoma w/o enlarged nodes?   My Dr. says my blood work does not indicate any blood disease and I shouldn't worry, but is it normal to have a cold for over a month?

Involvement of the spleen in lymphoma would definitely involve an increase in size. All the results show that everything is still within normal limits, and this is a good thing. That you are not taking any medications for pain is equally good. That you are not getting enough sleep which you report due to anxiety is not good. It is possible the cold is not improving because of this as well. Perhaps you need to discuss your concerns with your doctor. The best way to counter anxiety is to discuss them and to agree on approaches to perceived problems.
