I hurt my wrist doing a round off back handspring and it hurts to like push it back to a straight line like i can do on my other wrist and it is not swollen did i sprain it?

It's possible you may have sprained your wrist, especially if you’re experiencing pain when attempting to extend it. Sprains often occur from overstretching or tearing the ligaments, which can happen during activities like gymnastics. Even if there’s no swelling, it's important to rest your wrist, apply ice, and consider seeing a healthcare professional for a proper diagnosis and treatment plan.
