I have swollen lymphnodes  in my neck and groin and pain in my legs, mostly at night.  I have had blood work done, which was normal.  I have had 2 CT scans, chest and abdomen and pelvis, checking for lymphoma.  I have been told everything looks normal.  So why do I have these symptoms?  I have seen my primary care physician and a surgeon.  Who else do I go to?  Thanks
