I am a 30year old male and I recently went to the doctor complaining of a regular mild ache in the lower right pelvic area around where the kidney is. Sometime the ache is toward my flank but mainly in front. The doctor ordered blood work and a CAT scan with contrast for the Kidney and Pelvic area.

The CAT Scan came back stating scattered lymph node seen. The radialogist and the doctor ave told me I need to have another CAT scan in 3 months to see if the nodes are growing.

What exactly does this mean? Are pelvic lymph nodes a normal occurance ?

Also note that I have recently been experiencing a change in bowl movements which I am not sure is related..

Any information would be helpful, thank you in advance.
