Hi there, a few days ago I started having this excruciating pain right at the lowest point of my back/ the top of my butt crack. I originally thought I pulled a muscle from sitting on the floor too much, but it's starting to get more swollen. I've had cysts before, and it doesn't feel like my others did. I have a constant pain, but it's almost unbearable whenever I walk, sit, move between sitting and standing, lie down, and worst of all I am having trouble sleeping because of it. Does anyone know what I have? Or some good sleeping positions that won't make it hurt?
