Hi Lynne
Sorry to hear that your husband has myeloma and is suffering just now with the treatment.
The nurses on the Myeloma UK helpline are a great source of advice and I would certainly advise speaking to them. If it is anything to do with myeloma, they have probably seen or heard about it before, if not they will find out!
I was diagnosed in 2013 ( age 59) and had the CTD initial treatment which included cyclophosphamide.( 10 lots of 50mg once a week). I felt pretty rotten during the treatment, weak muscles- fluid retention – lethargy, but it is hard to pin down what causes what. I can say though that once the treatment stopped I did see a fairly quick improvement, certainly within a couple of weeks. I tried and keep as active as possible even if it was struggling to walk short distances.
I also think you have to be careful trying to draw comparisons because the dosages and timings can vary.
Hope this helps and your husband improves soon. Good luck with the stem cell transplant.
