I have been cursed with Psoriasis

[mataribot]

They are typically small, but every once in awhile they are bigger. They don't rupture unless I scratch them when the scale is present. It basically looks like a pimple the scales over with my P. The whole process doesn't last very long. Again, im told not to worry about unless it happens again (it did). I don't know if I should tell my derm or not.
