Psoriasis in ear canal, with frequent wax build up

Hello, I've scalp psoriasis for about 25 years, the past 2 years it's been at it's worst. However, 2 months ago my ear felt blocked and I got it micro-suctioned. I'd never had an ear wax issue before this. 5 days later my ears were blocked again, so I went back. This pattern has repeated, and I've now had micro-suctioning 6 times, in about 7 weeks. On the 4th visit I was told to use E45 for the dry skin in my ear, which I used for a couple of weeks, and the skin in my ear doesn't feel dry now. On the last visit I was told there was lots of dry skin built up in my ear, as well as wax. I was told to get 1% hydrocortisone cream from the pharmacy and use twice a day. I've been doing this for a week now, but my ear's blocked again. I have an appt with my GP on Friday. I think the psoriasis must be in my ear canal. Has anyone used drops or a spray that has helped clear this? The muffled hearing is driving me mad, and I can't keep having micro-suctioning. I'd really appreciate help to make sure I get the best treatment for this. Thanks for reading, and best wishes to everyone.
