“fine” throughout day, but terrible aching as soon as I lay down to sleep or rest

does anyone else deal with this ?

when im up and moving my body, i feel “okay” at least im not in that much pain, but AS SOON as i lay down to relax or sleep for the night, its like all the muscle aching & body pain comes out of hiding. i can barely move & everywhere i touch theres achiness x100

like isnt sleeping supposed to be for recovering from the day 😭 ?? i just want some rest !
