Anybody ever have an itchy nexplanon?

I've had my nexplanon for nearly three years at this point. I recall it being a little itchy/achy when I first got it, but once it healed I've honestly hardly noticed it.

Except for today, my arm has been so itchy- only where my nexplanon is, so I don't think its a detergent reaction or fabric reaction or anything. Again I've had it for years, so I'm at a loss on what could be causing this!
