Hi Keith,
It is my husband Phil who has Myeloma and he also has trouble getting a full nights sleep due to the neuropathy he has in his feet from the Velcade he had as his initial treatment. He finds wearing socks to bed helps a bit. Also massaging the feet and legs with cocoa butter can help.
It may also be that your body is still recovering from the transplant and it may take a bit of time for you to adjust and get back into a routine. I know Phil never got a full night of sleep while he was in for his transplant with the various people coming and going checking vitals, giving drugs, etc, etc.
I hope the pins and needles go away for you soon, they can make sleeping difficult.
Megan
