HELP!

Brihanna
I was on the pill for 3 years and because of my family history of blood clots and breast cancer my new doctor told me about the Implanon rod. A few days later I got it in. 
It's been 3 days and I have regrets. 
It burns then I get massive pains in my shoulder, my hand gets a burning sensation. This morning I woke up feeling incredibly nauseous. Even as I'm posting this it's burning and hurting. 
HELP! It's been 3 days. I got it on the 27th of this month. I'm 18
