Weird psoriasis?

[gigiischeese]

I'm not too sure what kind of psoriasis I have. I get weird flare ups. Sometimes they're minor. (Red and white flaky) Other times they're red/yellow/ and when the stuff plagued on my neck falls off it's hard as a rock. Right now I have a very bad flare up. It's pussy and has hard yellow stuff falling off it and it hurts to move my neck. (I only have it on my scalp and on my neck.) My scalp seems to be the worst effected area and my neck is very minor. Would anyone recommend bag balm for this?
