text: he's a teacher. if you trust him 100% and have a good student/teacher relationship, there shouldn't be any issues with asking him. ask him before or after class, if he's not your teacher, then ask him right before or right after school. he's there to help and support you. most teachers are because they want to help kids out.\n\nhow to approach it? "mister smith, i hurt my knee the other day ding something and i'm kinda scared to tell my parents about it because i don't want to get in trouble. do you think i should see a doctor about this?" he'll probably say, "well, let's take a look at it...."  and he will let you know what he thinks. he may lecture you for not wanting to tell mom or dad, but, that's because he's a teacher and he cares.\n\ngood luck!
