I hate getting out of bed after I've been sitting/laying down for a while. Whenever I try to get up out of bed its like a turtle trying to roll over off its back lol and as soon as I stand I get the sharpest pain in my lower back on butt bone. I always feel like my hips aren't gonna support me when I stand. And then when I try to walk after getting up my pelvic bones feel like they're scrubbing against each other. 😩
