Thanks everyone!
Ditto Mike, would be brilliant if everyones just cleared!! I wish for that too. My elbows and knee's are the most stubborn.
This is my probably quite vague and uneducated thoughts on it all.
Trauma - Psoriasis triggered. Like any significant traumatic event that the body suffers and causes it to go into immediate emergency action, which could be psychological, infection/ disease.. etc. This event could also switch it back off again in some cases?
My Psoriasis developed after a bike crash when I was 8 which was a sudden impact, maybe even the gravel I landed on that cut my elbow up badly caused an infection which is still ongoing 26 years later

I met a women when I was in hospital about 10 years ago and she was telling me she had Psoriasis for years when she was young which started after she nearly drowned. She suffered from sudden paralysis, which unfortunately she'd had an episode while she was out swimming. She told me her Psoriasis cleared after she sadly had a misscarriage years later

Once the Psoriasis has been triggered, it remains active as it is caught up with the T-cells that are actively fighting say an infection, another disease, cortisol ie in stress, so if those health issues are repaired the Psoriasis maybe clears/ improves?
Maybe, for example, this could be why some people say diet has helped them as the diet has fixed another health issue(s) which the Psoriasis was caught up with trying to repair??
Sorry if that is all vague, or rubbish, but I'm no Doctor, scientist..etc, just someone trying to get there head round Psoriasis
