Hi Gina
Your mum must be feeling low just being anaemic ,a blood transfusion should make her feel much better,until they decide treatment.When will you know what comes next Gina.
May be if you do some research to see what other drugs they use for Myeloma it might help,Hope your mum gets some blood as nothing worst than feeling washed out,and let hope the dex gives your mum some energy.
Love Eve:-)
