My Dad was diagnosed with CLL but had no symptoms for about 11 years. However, things moved quickly when symptoms did appear. He was started on FCR but it was not as effective as the Dr had hoped. (He had 3 doses.) he then had Rituximab and Bendamustine but again, his lymph nodes and spleen are still enlarged and the Dr says it's not looking typical of CLL. He's had a full CT scan, bone marrow test, etc... He starts Immunoglobulin next week as his immune system has taken such a battering and he has had cough after cough where the antibiotics haven't really touched it. He is so tired and sleeps constantly. What else might be going on? Any advice?
