I have a big gash on my forehead which is now a scar, got it from trampolining where a pole sprung about 180 degrees and bashed my head, this happened almost a year ago.
was surprisingly still conscious from it happening and i felt no pain, not dizzy and i was not nauseous - I'm a qualified first aid'er so i did most of the cleaning and bandaging on myself since non of the people who i was with at the time knew what to do but they did what they could - really awkward moment was when i was walking to my mothers car, i saw a trail of blood from the sports hall from where i was walking. When i went to the hospital, the doctor let me see the gash in the mirror and it was baaaad... the doctor said i was lucky i wasn't paralyzed or suffered anything really bad in the near future.
so yeah... i have a harry potter scar ;)
