OK I Have A Nexplanon Implant And The Doctor I

OK I have a nexplanon implant and the doctor I had to my knowledge I felt like she didn't not do it right BC it majorly hurt and if I moved to quickly or move my arm up i felt like i was going to pass out and i have a bruise that covered my whole back part of my arm and the it took a long time for the bruise to go away what I'm getting at is I think it was put in too deep or wrong it moves down to my elbow quite often and when it moves it burns and itches should I have it checked out or have it removed also having headaches and blurry vision
