I don't know how old you are but I know as I've gotten older, just turned 48, I simply have more aches and pains. My husband has too, and we both agree that we don't feel them until we try to relax. I think when we're working or focused on a task, we just don't notice them as much.
I too am a worrier and have a lot of anxiety so I think I hold my body tense and that may attribute to the aches and pains.
For me it's probably some of both. I did go on a vacation recently also, and did not feel the normal aches and pains I do when working.
So I guess my answer would have to be "yes"
