Hi,
Muscle pain and weakness can last for awhile. I don't think I was back to normal for about a year. I finished chemo in August, went for a follow up 3 months later, and was so concerned about achy, heavy legs that my oncologist ordered a bone scan just to be sure. I did not gain weight during chemo. Afterward, my radiation oncologist encouraged me to start walking. She said just start with 5 minutes if that's all you can do, but add a minute every day or so. This has worked well for me and the news I hear now about exercising after cancer treatment sounds encouraging. Congrats on finishing chemo!
