Hi Jadey, welcome to the forum. I have never had radiation YET, but I may in the near future. I have been told though, that being constantly fatigued is one side effect that pretty much everyone has and that was told to me by the people who give the radiation treatments and also, patients who have received them. If this is really a serious problem for you though, I would suggest you contact your treatment team to let them know this is happening for you. I know there are many people here on the forum who have had radiation and one of them will likely respond to your post shortly.
Good luck with your treatments and come back on here whenever you feel up to it and let us know how you are.
