What Causes Swollen Leg And Abdominal Pain When Diagnosed With Groin Lump?

I have 2 (Two) very largely swoiien & still growing lymph noids ... A biopsy of 2 (two) spesimons was taken from ONLY ONE OF THE 2 very largely swollen & still growing lymph noids ... Both of these 2 lymph noids are located on the most upper part of my right thigh in my growing area ... The biopsy was taken from the lower one of the two, (located more @ the upper thigh,,, than the upper lymph noid is more in the growing area just above)... The Lab work came back two wks. ago with only 5% of any explainable infomation (95% info ununderstandable as to what it was or any knolage of what it could be)... I ve told my Dr. Of the painful symptoms I m experexing , the sever swelling in my compleat right leg (down to the toes), the pains in the lower right side of my addoumon (apindex, intestinal, & right side of stomock area), the big change in appetite, weight loss, body fever, energy loss, bowel moments, ect. ... I have my next Dr. visit Oct. 7, 2015 (1 1/2 days away), I don t know what to think or feel about what the Dr, HAS NOT TOLD ME, all I ve been told is its very bad lymphthomeomia & he doesn t know where the cause is from.... I feel way too much in the dark !!! How / more should I feel or be told of my condition & lab results ?????????? V. Bass Sr. YYYY@YYYY
