My husband had his last zolodex injection in late April - being a treatment for prostrate cancer. He has suffered from weight gain and severe lower back pain, which restricts his mobility a great deal and also muscular spasm attacks. His oncologist has told him that this is a known side effect, but we can't find any really informative detail as to what to do to remedy the situation. His oncologist has told him that it may take until January for the Zolodex to leave his body. We are desperate for help. Can anyone offer any suggestions please? Has anyone else suffered like this?
