My husband recently went through CAR T therapy (Carvykti). He is about 4 months post-infusion. He spent 21 days in the hospital with some CRS and HLH. Since being released he experiences severe muscle pain. His strength is not nearly what it was and experiences mild full body muscle pain during the day and at night some targeted intense muscle pain in his shoulders. It doesn't seem to be improving. He is also pretty foggy in the head in the mornings and night with very limited emotions. Anyone else with similar experience? Wondering if it will subside with time or if further treatment necessary?
