A fake medical document at MEPS?

Okay, so please tell me i am not the only one who thinks this sounds crazy and shouldn't do it. I have some scars on my arms, particularly on my forearms (not from self mutilation, they don't look like that either) but I never went to a doctor when it happened, just slapped some butterfly sticthes on it and called it a day. I told my recruiter this, and he said unless I have medical documentation of what happened, they will probably think I am a cutter. Uh, WHAT? I guess it happens so much that scars on your arm people automatically point and think I'm emo or something, yeah, no. That's not the case. My recruiter actually suggested that having a medical summary of what happened, when it happened would be the easiest route and if Ididn't have one, to come up with one, but wouldn't making up a file be COMPLETELT AGAINST THE LAW? Is he crazy? Wouldn't they find out? I'm not sure about this and thinking of just finding a new recruiter. Please let me know your honest opinions, thanks!
