I have been cursed with Psoriasis

[Fred]

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.

Sorry but I'm not sure, have a look at this thread as it has the different types of psoriasis and links to images: https://psoriasisclub.org/showthread.php?tid=56

But yes if your dermatologist said to contact them if it happened again and it has, then you should definitely contact them. It may be something and nothing but best to get professional advice I think.
