Psoriasis not going away?

Hi all, this is my first post on this forum, I’ve been reading through and it’s nice to see many others in the same boat as me even though I wish you all the very best with your treatments and conditions! My story. Around a year ago I noticed a small, dry circular patch of skin on my right upper arm, didn’t think much of it and left it alone, a few weeks later i noticed another small, dry circular patch on my stomach, then even more patches started to appear on my legs, arms, chest, back, scalp and face. I went to the doctors and the doctor initially diagnosed the patches as ringworm and gave me some cream which did absolutely nothing, so I went back a month later and it was then he diagnosed psoriasis. I wasn’t massively shocked at this news because my mum has eczema and my brother has psoriasis however trying to pinpoint the trigger is what confuses me the most. Recently though I keep seeming to get more and more random patches, it’s not “traditional” psoriasis as, funnily enough I don’t have any on my elbows or knees, but they appear in completely random places. One on my left shin, one on the outside of my right lower leg just above the ankle, random one half way down my left forearm, one on my left hand, side of my thigh, shoulders etc and are just individual circles rather than large scaled areas. The ones on my body don’t bother me so much because I can cover them, although I do worry that eventually my whole body will be covered in it and would still like them to go down or away, even my girlfriend jokes and says I’m a Dalmatian. I’ve used various creams, E45, Cetraben, Calcipotriol Ointment, Betamethasone Valerate etc, none of which have done anything really. The ones on my forehead/hairline and scalp are the worst because they’re the hardest to hide. I struggle using T-Gel because frankly it stinks and doesn’t actually do anything to treat my scalp, I could deal with the smell if the product worked but it doesn’t. I’ve also used Nizoral which doesn’t smell at all but again, does nothing. I’m 25 now and realise I’ll probably be dealing with this for the rest of my life although I am wondering whether it’s better to go to a dermatologist for some “stronger” medication. I’ve quit smoking to see if that helps, rarely drink alcohol, exercise regularly and drink plenty of water, all of which is apparently meant to help ease the psoriasis but nothing seems to do anything, I’ve only quit smoking for a month so maybe it’s too soon to expect to see any difference but you never know! I don’t feel stressed about anything and I’m a pretty laid back guy, so I’m trying to find out what my triggers are and avoid them, I just don’t know what they could be at the moment! Anyway, apologies for the long winded post, any advice is very much welcomed! Also happy to try different treatments, my skin is already ruined so I’m not bothered if anything makes it worse 😂 Thanks for reading. Flakin’
