Weird neck bump

Whitney

I’ve had it a month and it started like a pink mole or skin tag. Didn’t think it was a zit because it was numb (?) normally when I touch a pimple it hurts or I feel it. Not with this one. Then it got bigger and redder. Bf popped it because there was a black thing in it and something hard and white come out. Now there’s a red streak across it. I was in the hospital a couple weeks ago. Dermatologist can’t see me til November and regular dr can’t see me for another week. It itchesss!!! And the streak is what worries me. But I don’t wanna go to an emergency room and be told it’s a zit. 🙄. Any idea?
