"having read all reviews onsite i went ahead and had my implanon inserted a week ago. yes its early days and this is reflected in the rating above for now as a new user. but i feel its important to let others know my experience so far. it was inserted without any trouble by my gp, and with the local anesthetic i didn&#039;t even feel a thing. when this wore off yes my arm is bruised and was very sore for the first 48 hours but it is slowly getting back to normal now. at present i have very mild headaches on and off, and lower back pain, but not enough to need to take anything to ease it. so all i am saying is when you are putting hormone into your body yes it will clearly take a while to settle down."
