I get that too! I use the round part of a Bobby pin. Feels so good but be careful lol
I have and I itch them and now I'm 33 weeks and I have a bad rash on the back of my ears. Idk if it's related to the inside itching, I have yet to talk to my doc but it hurts. I also wear glasses which I think contributes to the itching in my ears. Lol good luck! ♡
