One other thing, I don't know about the others but we are about to have a change of season, this ALWAYS upsets my skin and makes me very itchy.

Yep indeeed beginning last week I had quite sore feet even spinning was painful by the end of the lesson, and what appeared? The weather over here took quite another direction.

Although you have no sun in the UK your still need vitamin D3.
Between 5 mcg and max 50 mcg per day is necessary, and is very helpful for health overall and therefore also for the psoriasis.
