Psoriasis flare up questions

[Fred]

you have to consider whether your trigger is causing your psoriasis or whether your psoriasis is causing your trigger.

Good point it can become a vicious circle and sometimes difficult to stop, feel down and psoriasis gets worse, psoriasis gets worse and you feel low, and on it goes.

I've given up trying to work out triggers as sometimes I get a flare up and I can never pinpoint it to anything, then sometimes I've thought "That will make me flare up" and it doesn't.
