From Anna,
Hi
NewGuineaChild, Others have probably already answered you but your brother must have misheard cause this cancer does cause bone pain. I have many links about MM if you'd like them let me know. They will be helpful I think. I don't want to overwhelm you but if you'd like them. Just say so and I'll send them to you. My Dad has had MM for 10 years now.
Your friend,
Anna
