Hi Maureen
Velcade takes a little time to get going,so try not to worry,light chains,can vary,we no longer go by light chains,as they did not show a true reading after Thalidomide ,they read normal,but BMB showed it had gone up to 80 percent in bones.
I now tend to go on how Slim feels in himself then wait for BMB results,his has gone down to 10 present in bones,but as you know,we have extra problems.
At the end of the day,you will become an expert on Ian,so use you own judgement,Love Eve
