Enlarged Lymph Nodes

Hi I am just wondering if anyone else has trouble with enlarged lymph nodes. I have a small one in the groin & a large one under my arm. The underarm 1 was biopsied & scanned but was not malignant & I think I have asked before but will ask again (sorry) but has anybody else have unexplained weight loss but still eats or maybe it is just from living with constant pain? Thanks in advance, all I can say is I am so glad I found this support group:)
