Is there a difference between sprained and strained?

nearly a week ago i did something to my wrist but idk what. its been hurting when i move it. and i cant bend it just a little back without there being a strike of pain. my friends said it might just be strained and i kinda agree but no one really knows. and unfortunately theres a bunch of clueless people in this world and no one seems to know the difference between those two. ima get my wrist looked at by a doctor today though.
