Owww I want sleep

I have chronic pain and my doctor can’t figure out what’s wrong and it’s just been escalating. My whole body aches like i just got out of track practice, and im trying to avoid painkillers because of liver damage(I rely on them too much just for headaches) but it’s getting hard to sleep without it. I can stand powering through it throughout the day but at night it’s the only thing I can think about.
