Open wound/scab on ear and stuffy breathing! She won’t stop scratching herself up :(

Hello! My cat cinnamon(12-15ish) has been scratching her ear and face up over the past month. We have been to the vet about it and are waiting on the lab results and they told us to put neosporin on the wound and soak the scabs off. She just keeps scratching it

We have tried everything to get her ear to heal. She’s been in a cone. Making sure it doesn’t scab and always having neosporin on it. I bought padding and bandages but nothing would stay on. The last two days I’ve left it alone it see if that would help and it has scabbed up already.

Now her breathing, She has always had upper respiratory issues which we have had treated but within the past week her breathing sounds extremely stuffy, i can hear it when she is just sitting next to me.

I’m just kinda lost with what to do. I’m definitely taking her back to the vet soon but wanted to see if there was anything I could try at home in the mean time.

i know this was a lot to read, thank you!!
