I am sorry you are experiencing pain from bone metastasis. I would not take anything without discussing with your oncology care team. I am not sure if you receive care at Mayo Clinic, but at Mayo Clinic there is an Integrative Oncology team that can be ordered by the oncology care team to help people with cancer feel better by reducing the fatigue, nausea, pain and anxiety and other symptoms that come with cancer and cancer treatment. Have you ever heard of Integrative Oncology before?
