Hey so I have really bad joint pain. I've had it on and off for awhile but now it's pretty bad, preventing me from sleeping, and making me almost nauseous at point while trying to sit in a metal desk at school. My bones pop and crack a lot too. What is up with this? Can it be eating disordered related? Can I make it go away? At points in my life ive been severely underweight as well. I'm only 19 but I feel like an old person and it's concerning me. Has anyone else experienced this?
