Is this pustular psoriasis?

have very minor psoriasis (it is never thick, doesn't flake and I've never had a patch much bigger than a coin) and less than 1% of my body is covered but recently I have noticed I am getting small pimples appear on my legs, mainly on the calves. If I didn't have psoriasis I wouldn't be at all concerned about them but because I do and have heard about pustular psoriasis I'm wondering if that is what it is. The only treatment I've had for psoriasis is topical creams, namely Dovonex and Dovobet. I use Dovobet once on Saturdays and Sundays and Dovonex twice a day on week days. I know a side effect of topical steroids is folliculitis and I'm wondering if it's that? I have noticed there has been a hair coming directly through the middle of the pimple a few times but it's not always the case as you can see in the pics. I have to admit I sometimes lightly prick these pimples with a sterilised needle and gently squeeze them after which they disappear after a few days. I've never had more than two at any one time but a new one will pop up every few days or so. I've had some appear in places that I have definitely never applied any psoriasis creams to. Here is a couple of pics of two different pimples on the back of each leg. https://postimg.org/image/pkuci1li1/ https://postimg.org/image/6kd2nmpl9/
