Question: how long does it take to get your energy back after chemo and radiation?
Answer: Any chemo drug can cause you to have fatigue. It lasts for a few days in some people, while others say they have it throughout treatment or even afterward. Radiation can give you fatigue that tends to get worse over time. It usually lasts 3 to 4 weeks after your treatment stops, but it can continue for up to 3 months.
