Hi I suffer from scalp psoriasis. I only developed it in my mid thirties (42 now) and I generally keep it under control by use of steroid ointment (used only sparingly when necessary) and medicated shampoo. It's the oddest thing....I don't have it anywhere else, thank the lord but worry in case it spreads. My worst episode was a couple of years ago when I thought my scalp was on fire!! My GP wasn't really that helpful but I personally believe it's caused by both a mixture of diet and stress. I also have arthritis but my doc has yet to make the connection although I know there is psoriatic arthritis!! Mind u I too have an egg intolerance so that's interesting???? It's a dreadful condition and I count myself lucky I only have it on my scalp.
Ahh I've had the scalp on fire thing too...on occasion I used to have to cover my arms with bandages because they bled so much
Its the worst sensation!!! And scalp psoriasis is such a pain with its flaking and gettin on
I also have psoriatic arthritis, IBS, and Raynaud's phenomenon (which are all associated). If you have a dermatologist, you should say you've been having joint problems and ask to be referred to a rhematology specialist if they can. Any good specialist should be more than happy to send you on for an assessment
I know a lot of people with scalp psoriasis only, seems to be pretty common!

Just as an FYI; Psoriasis isn't caused by bad diet. You won't get psoriasis by eating badly EVER, it's genetic. It can stay in your genes for a lifetime without making an appearance if you never get the infection that triggers it.
The only thing a bad diet/stress etc will ever do is make existing psoriasis worse.
In 2008 I had a PASI score of about 65 (out of 96) and I was critical because psoriasis can affect temperature control and heart function when its very severe. They put me on a few drugs which did nothing, then I got onto Etanercept, which has put me into complete remission. (pasi score of 2!!) Years and years of silly diets, creams, uvb light therapy and drugs which did so little! I've had mine since I was 4.. so its really weird for me to have nearly normal skin heh ^_^
