Okay kiddo, let's talk about sequela. Sometimes when someone gets sick or injured, it can leave behind some problems even after they get better. These problems are called sequela (say: "seh-kwel-uh").
It's kind of like when you get a really bad cold or flu and it goes away, but you still feel tired and achy for a little while longer. That tired and achy feeling is a sequela of being sick.
Sequela can be all sorts of things. They might be physical problems like a scar from a cut or a limp from a broken leg. They might also be things you can't see, like trouble remembering things after a concussion or feeling sad after something really scary happens.
The important thing to know is that sequela can happen to anyone and it's normal. It just means that our bodies and brains need a little extra time to heal and get back to normal after something bad happens.
If you ever have a sequela or know someone who does, it's always a good idea to talk to a doctor or grown-up you trust. They can help you figure out what's going on and how to feel better.
