My father has MM. He was diagnosed in December 2022 . He is 84 and is on monthly maintenance, which includes Revlimid for 21 days. He sometimes experiences shakiness in his legs and then sudden weakness where he can’t hold himself up, that he ends up falling. Luckily he doesn’t break any bones, but cuts and lots of bruising. We have brought this to the oncologist’s attention, but says she is not aware of this side effect . Has anyone else experienced this?
