My husband was treated with 6 rounds of FCR-Lite, he finished his treatments in July and for the las 3 or 4 weeks he has had a severe cough and went to his family doctor and was diagnosed with a sinus infection.  Could this be a sign of a relapse?  He was running a fever aroud 99 to 99.8.
Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about relapse at present.FCR lite is chemotherapy for CLL (chronic lymphocytes leukemia). Chemotherapy can cause immunosuppression and Sinus infection. So give him broad spectrum antibiotic like levofloxacin or azithromycin. Telling him to do steam inhalation 4-5 times a day and Chat Doctor. Don't worry, he will be alright. Don't think about relapse. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
