Patient discussion about methadone
Q. I would like to chat with someone w/any knowledge of fibromyalgia being treated with Methadone my best friend has severe fibromyalgia and has been treated with Methadone for the past several years. She has developed severe chronic anemia in these years. She now has lymphoma. I want to know if she is the only one and if methadone can affect bone marrow.
the Anemia is probably due to the Lymphoma. if not-her life is out of balance, she might changed her diet and may have shortage of iron or B12.
