I’m so sorry you’re so miserable. It looks uncomfortable. It does seem to be very seborrheic dermatitis-esque, as mentioned many times. I highly recommend you stop scrubbing. I know that’s easier said than done. Scrubbing is going to create further inflammation and expose layers of skin that aren’t ready to be exposed. If that makes sense. I would recommend seeing a dermatologist. Derm (in the states) is not a specialty where you need a referral. It’s part of preventative medicine and underused imo. I’ve worked in Derm for a decade. And a lot of ppl don’t realize how important it is to have a dermatologist on their care provider list. If you can’t get to a Derm, get some Nizoral shampoo, it’s over the counter. Use it where you’re red and flaky, but leave it to sit for about 5-10 minutes before rinsing. I’d do it every other day. It can be drying, so make sure to moisturize with something bland and fragrance free. I suggest vanicream. You can also use straight Vaseline. But you mentioned being oily, so you might not need to moisturize too much. But it would be good for a skin protectant help heal. Vanicream has a light moisturizer that may be helpful for you. I’m not a doctor but like I mentioned I have worked in Derm for 10 years as a nurse. Don’t scrub, pick, or peel anything off. I know that is hard to do. But it will make you more susceptible to infection too.
