Hi, In May 2021 I was told I have SMM. In Nov 2023 started on Darzalex, IVIG nothing out of the usual and outside of minor stomach distress was doing fine. In Mar 2025 my platelets dropped and even with the normal course of drugs have not improved. Currently my platelet counts are averaging around 15,000 when I receive platelet transfusions. Next week I’m scheduled for radiation on a spot on my back. Outside of being tired all the time I have no bone pain. I’m a semi-healthy 81 year old male. Seeing little mention on this forum my question is this something that other people have experienced?
