Hello! I've noticed that when I get up after sleeping or lying down for a long time, there's a strong burning sensation in the top of my abdomen, right where the ribs meet in the middle, like something is cracking. It feels like the skin is being stretched at one point, or something very hot is burning in the middle. Has anyone experienced this? What could it be?
