Hi there - try not to worry about the aches in relation to the cancer, specific pain in a specific area is different of course but and achyness all over probably isnt anything to worry about. I wake up stiff in my neck and tongue and cheeks very morning partly cdue to lymphedema and partly due to sleeping and not using those damaged muscles while in bed. (I sleep like im unconscious these days!! I was told thyroid issues could crop up at the 4 month mark. I'm past that and a perky turkey! So I think I'm okay so far. The 4 month thing was told to me by my MO - hopefully it's not the case with you! Good luck next week - will say a prayer you are all clear! . Have them do bloodwork for your thyroid - hopefully they took a baseline prior to treatment. Hugs!
