Is there a cancer survivor out there who has any experience or knowledge regarding the long term use of Erbitux or knowledge of extreme fatigue in remission? My son is in remission from a bout of Stage 4 SQ tongue and lymph node cancer. He had a second cancer in his neck from which he is also in remission. He is now on Erbitux, infused every other week. His total time on it including his time on full Chemo (2 other drugs) is a year and a half. He has extreme fatigue, and the usual other side effects, including rashes and infections in his toes and fingers. Again, what I would like to know is anyone who has experienced extreme fatigue a year or so out of chemo or anyone who has been treated long term with Eribitux.
