Is it normal for my buttock to be ITCHY after buttock implants?

Itching is fairly common after surgery.  If there is any sign of rash or allergic reaction, that would be something different.

Itching can be common after many operations, since localized inflammation can cause itching. Sometimes small sensory nerves that are recovering cause itching as well. Buttock implants require fairly close follow up, so make sure you are getting in to see yoru plastic surgeon soon.
