HI, I’m guessing that he’s an older patient because he’s having Lenalidomide from the outset? Of course I may well be wrong but I had a stem cell transplant at Christmas and am one of the first patients to receive the drug afterwards. I do have a friend who’s 72 and he’s doing ok, and has had it prescribed from the outset. I’ve been suffering with my feet as the result of large does of chemo (bald head but am soldiering on! Not heard of percentages as such, however I have lambda light chain paraproteins with a P53 mutation. This MAY make it harder to treat but so far my levels have come down from 3,000 at diagnosis to 58! (as I understand it this is how active the cancer is). Suffice to say that if there is one thing that’s certain with Myeloma, it’s that nothing’s certain! Six months on and I still get an aching shoulder blade and sore ribs, when I first fell ill my shoulders hurt after decorating and there was no skeletal damage there! P.S. I’m not a fan of Facebook, so won’t be going there……Hope all this helps, good luck.
