if you mean your getting tested for allergies by getting needles and that stuff i wouldnt know anything abt it. but sister did it and she was maybe 9 yrs old. you will be ok :D unfortunate that you have to get this DDDD: I wish you good luck ;)
Honestly bro thats nothing compared to what i have had. Just get it over and done with and dont think about it too much. Also tey not too over think it. Hoped this helped
