Did you experience fatigue after receiving CAR T-Cell Therapy?

"My strength slowly returned at what felt like a snail’s pace. I remember still being so fatigued at my thirty-day appointment and asking my oncologist when it would let up. By my sixty-day appointment and another clean scan, the fatigue was finally letting up. There is a small hill on a road near my home that I walk with my dog almost daily. I could only make it to the base of the hill and could not climb it, but I finally graduated up to climbing that hill again. "
