There’s a whiny, panicked toddler inside my head. It’s 3am and I am jolted awake by a massively painful leg cramp. The kind of sudden, unexpected pain that makes your eyes water and throws your whole body into a panic – even more so when you were deep in REM sleep just seconds before. I get up and put my foot flat on the floor to stretch the calf muscle. I’m a grownup; I know what to do. The pain is excruciating, and in the back of my mind there’s this toddler whining “make it stop, it hurts.”
