My husband is 58 and has had a stem cell transplant and just recently CAR-t with Carvykti. His stem cell only lasted 4 months before the cancer came back. The side effects from Car-t have been awful. His case is complex. Has anyone else had this with side effects? He was in ICU for CRS and now dealing with bad neurotoxicity. He had the severe headaches and now has numbing in his abdomen, back, feet and hands. Has anyone else had this? He is a month past the transplant.
