I can relate lol. I have that from time to time as well like an EEEEEEEEEE like you said 😂 I also got some itchy ears pretty much everyday so I was thinking maybe I have a lot of earwax that need to be cleaned like those you see on Youtube. But when I came to the doctor, my ears were normal. I told him about my PTSD as a possible cause and he said to check to a psychiatrist for that. He said the itch is only because I kept on touching them, so the stimulation causes it to itch. Good thing there was no earwax pushed there cos I use cotton swabs a lot.

Sorry to hear it's getting bad for you. Since the doctor didn't ask or have you tested for some blood work, they're probably not related. Hopefully there's more study about it, it gets really annoying at times. :/
