Help! Debilitating Fatigue

Hi all-- I have had debilitating fatigue for over a year now. We discovered I have a thyroid disease; however, even after months of having normal numbers, the fatigue has persisted. About four weeks ago hard, painless lymph nodes popped up in my groin and my neck and are continuing to grow. Furthermore, I have had a fever of 100 degrees for 3 weeks. My blood results showed a 13.2 mg/l for C reactive protein, low MCV, high neutrophils, and relatively low lymphocytes. I have lost 9 pounds in two weeks. I am studying abroad in Spain, and the doctor I met with said it is probably just a throat infection and to take antibiotics, but my throat doesn't hurt and neither do my lymph nodes. I was wondering if anyone had any insight or comments, because I know these are all the symptoms of lymphoma... I am meeting with an American doctor next week, but thought I would post here to see if I could receive insight before then.Thank you!
