I have Multiple Myeloma since 2007. My current advice is to add Velcade to my already dexamethasone and Revlimid. The later I was on from July 2007 for 20 months and then nothing until my numbers went up from an average of 800-1000 to 1600. I am concerned to add this medication because of the many side effects. I am 72 years old and feel good except for my degeneration of my lower back which keeps me from walking without a walker at this time. Thank You
