I had Implanon inserted at the end of December '09. It has been fantastic! However, about a week and a half ago, I began itching something terrible! I don't have any (known) allergies, but my initial thought was that I was having some sort of allergic reaction. The next morning, my chest and arms were covered in red bumps (they looked like pimples). The itching has lessened, but I still have these red bumps all over my arms, chest, and back.
Now, I realize that the most obvious answer is this is acne. However, at 24, I have never had problems with acne (not even as a teen). Would acne as a side effect of the Implanon take 3 months to set in? What else could be going on?
