Butt Plug Tear/Itch

Aaspens 🌞🌙

A couple months ago, I was putting in my butt plug and I put it in too fast or didn't use enough lube and it kind of hurt, so I'm pretty sure I tore it, resulting in an anal fissure.

My butt hole has been itching 😹🙄 for a while, now, and I'm wondering if this is a symptom of a fissure? Has anyone gotten this from a butt plug/anal?

How to treat them naturally?
