"i just got this thing in 3 days ago and i have a severe infection where it is. also i noticed it move onward towards my muscle in my arm. i had the implanon and. ever had these kinds of issues. in fact i never had issues with the implanon. this nexplanon is horrible and don&#039;t recommend anyone getting it. they shouldn&#039;t change things that work well. this is what happens. being the implanon back."
