Hi,
Welcome to the ehealthforum and I am really glad to help you out.
All your symptoms are pointing towards the possibility of infectious mononucleosis only. However to confirm the diagnosis, get a FNAB (fine needle aspiration biopsy) of the lymph nodes and swollen glands. FNAB is aspiration of the material of the glands which is done by a fine gauge needle (22 or 25 gauge) and a syringe. This will confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
