Нога затекла / свело ногу in English
Hello everyone!
Could you please help me with these two expressions? What do you call these feelings in English?
1) "Нога затекла": e.g., when you sit in an uncomfortable position for some time and then stand up, you have to do something (jump on your leg maybe or have a walk) because one of your legs is... what? My dictionary says that "asleep" is the word but is it really what you say? A leg... went asleep...? Or what do you call it?
2) "Ногу свело": I've never experienced this but I've heard it happens sometimes: if you're swimming in really cold water, there's a danger that your leg becomes... what?... and you'll drown (or so I'm told...). If I understand everything correctly, it's much more painful. Does the word "cramp" fit here? Would it be "my leg got cramped" then?
