Hi Mike
Like everyone else I am sorry you have had to join us, but take encouragement from us "oldies" that as diagnosis isn't the end of the world.
It is interesting that, at the moment, a lot of folk seem to be being diagnosed because of back problems. Do take care. I am glad your boss is being sympathetic, especially as the majority of people, ourselves included, have probably never heard of myeloma before.
Very best wishes.
Mavis
