Swollen fingers and joints after waking up

Anyone else's fingers or hands swollen whenever they wake up? I have trouble curling my fingers, closing my hand, or making a fist. That causes pain in the joints. It's like there is some kind of fluid build-up in the joins while asleep. It goes away after being awake a while and moving around but then returns after sleeping again.

While most symptoms have declined after a couple years, this symptom first appeared around the two year mark. Not sure if it's from something I eat. I eat pretty cleanly these days. Any idea how to alleviate the issue?
