I am pretty sure I have impetigo on the back of my neck

I tried going to urgent care for it today because I moved and my primary care doctor is an hour away now and I don’t have the gas. They couldn’t take my insurance though so I am trying to find another primary in my area so I can get it looked at soon.

It getting bigger, it’s crusty and it’s itching like hell. It also won’t heal up and go away, it’s been there for a while.

So do I need to change my bedding everyday and keep it covered? I feel like I should leave it uncovered so it will dry out but if I don’t maybe it can spread?

If I catch myself itching it I stop and go wash my hands with hot water and soap. I’m washing the actual spot everyday too.

I promise it’s not a pimple. It started out as one but it’s been there for a week and a half with no improvement and it’s really gross and yellow crusty in the morning and makes me wanna itch my whole head off

Added: I got my insurance sorted out and went back to that urgent care and it’s definitely impetigo and he called in the ointment for me
