Hello Valerie,
I went through what seems virtually them same last year at age 62. I had Car T infusion August 1st.
Our take away is to believe what the doctors and staff tell you. I experienced all of the side effects they outlined. After day 2, I spent 2 weeks in the hospital, one week in intensive care. I remember virtually nothing of those weeks. Your mom will require all the care and support you and your sisters can provide. The therapy took a lot out of me. I was so thankful to have the family support I had. The doctors and staff at Mayo were extremely supportive as well. Never be afraid to call back to the station if you feel something is off. My wife feels it was important that she stayed with me 24-7 while I was in the hospital. Be patient, recovery took some time. I felt cold all the time for at least 2 months after the infusion. I experienced a lot of joint pain for at least four months. I found it difficult to eat for a long period of time. Nearly six months later. I can happily say I am doing quite well physically, I am taking long walks and am even back into participating in light sports. It was tough but so worth it.
All the best wishes from me to your Mom and entire family.
Bob
