My wife Christine is in remission following CDT treatment, which was discontinued 9 months ago. Her paraprotein reading is very low (less than 1), and she feels well. All this sounds very encouraging and the only symptom, apart from the ever-present fatigue,is slight back pain which is contained with paracetamol. However, she has been receiving monthly zometa infusions for the past year which the doctor has now discontinued because he tells us that her blood tests are showing signs of some kidney damage. How does this show in her general health? How serious is it? What treatment is available to deal with it, and how successful is it? (Our haematologist, whilst presumably very good, is hopeless at communication).
