I have been on the implant for 6-7 year. My 3rd insertion was a month ago. The nurse said she would move the new implant a little from the previous spot so it wouldn't create dead tissue underneath my skin. I didn't get it and let it go. However, since last month(April 28th) there is a small red circle on the old place the implant was. Within the circle it's white. I'm worried and wondering what it is. Is it common for this to happen? My last 2 insertions which were performed by a doctor, there was nothing wrong with my arm. Thanks in advance.
