About three days ago I was stretching and I don't have very good posture. so I thought if I stand a bit straighter I might fix it. I ended up stretching my neck upward a bit. Now I have pain when I look down. Right between my c3 and c4 of my vertebrae. I felt a bit of stiffness but the pain and stiffness isn't severe. I move my neck and other body parts just fine. My pee and stools are they way they should be, healthy. There's no internal problems. Everything is fine just that small pain and stiffness around neck and around jaw. Any advice? or if it's a ligament I pulled? Or inflammation? Orthopedic Soon?
Thanks in advance.
