My mom wants me to go to the pediatric, what do I do to get out of it?

Ok, so like my mom is like a super nut job! She wants me to go to the pediatrics (kids doctor), and take a physical exam, like I already did it 3 times already, and it's a painful and embarring process. Like who wants to lose blood, and have a painful middle finger, and the pediatric doctor saying,' you're as healthy as a horse.' That's so stupid, like seriously I just went 2 months ago, but that was when I was sick, but now like people only go there when they're overly cautious about their health, I'm going next month, and do you know what, I'm getting braces, and at least 3 or more shots, and that stupid exam thing, like why not just take out the exam, and I don't need that much pain in one month, it's almost like waking up one day and feeling nothing, and then the next morning you feel like you got hit by a truck. My mom is very cautious, and overprotective, what can I do to make her change her mind about bringing me to the physical exam? I need some serious help, but if you can't do anything about it just please say that you agree that my mom is the ultimate pain bringer. I love her and everything don't get me wrong, but I want choices of my own.
