I've had the contraceptive implant in for about 2 years now and for the last week or so I've been experiencing worsening pain where it is (feels like it's trying to force it's way of my arm) and now developed a bruise where it is too. I've got doctors appointment about it but its not until next month and I also feel very sick and tired which I'm not sure if it's connected. Has anyone had any experience with this happening, or if it's unlikely to be broken (I can still feel both ends) what could be causing the pain?
