Mine itched for a good month after I got it inserted. Now it gives me no problem x
I don’t remember getting itchy with mine, but it was a while ago just really sore maybe if it gets irritated use some rash cream or antiseptic? Just incase it gets infected
If it's relatively new it could just be it healing. I don't remember it being itchy for me but it was late teens and 20s I had them.
Yeah mine itched for a week or two when I got it.
