Hello Maureen,
Welcome to the site; although ideally you do not want to be here you will find the people friendly and a great source of support.
I reply simply because I have had a similar experience to your husband and I have managed to come through it. Although at the other end of the country I am of a similar age (54). I was diagnosed in May of this year with MM following back pain and a spinal operation to repair 3 of my vertebrae that had fractured.
I subsequently followed a 12 week programme of medication and I then had a stem cell transplant in September. Today I am 14 weeks post SCT and feeling pretty good. I too felt weak, but the strength does return.
So please take heart from my story and try to get through the festive period as best you can.
Good luck and stay strong.
Regards,
Tim
