He did well with the 3 days of chemo before the infusion, but he had done well with all prior chemo sessions. The worst thing he experienced in the hospital after the infusion was Neuro toxicity. He lost ability to form words or answer questions. Like a stroke. Thankfully, with treatment, he returned to normal over the next day or so. The whole process made him very weak but with Physical Therapy he gradually got stronger. The process is not easy but it killed all cancer cells in his body. Well worth it.
