awww. im sorry to hear about your alegeries... but the surgery reallyu isnt bad. they gave me laughing gass for about 5 minutes then put in the iv so i didnt feal it then i went to sleep. then i woke up and my whole face was numb from 10:30 till 9:30 at nite. its really not bad. just wait till your teeth are out and not impacted. thats when it hurt the worst
