Dermatology :: Pimples On Body

I've had these small pimples affect me for several months now. I suspect something std related, but currently my doctor has ordered a blood sugar test so I'm awaiting those results.

They are small pimples, they appear in one area and disappear after a day or 2 and appear in another area sometime. I get few other spots that a bit tougher and bigger, but not often. They can be itchy and also itchy even when there are no pimples, mostly in the thighs. I have had the pimples mostly on the thighs, but also legs, lips, and recently I've discovered some on my face, arm,  testicles and the foreskin of the penis.

Like I said I suspect std, most likely herpes. Herpes I know is a common and untreatable condition,but these pimple(at least on the legs) are continuous and does not herpes happen a couple of times a year?

I've been to a sexual health clinic several times and when they look at them shrug like it's not something they deal with or not recognise and therefore they do nothing. This clinic doesn't test for herpes as procedure, but I did manage a swab test on a pimple on my lip which was negative(however it was a burst pimple i.e. not a good sample). People that look also seem to not think it looks like herpes.

Basically what I'm doing is exhausting all possibilities because I don't want continuous pimples on my body. I can deal with it if I'm going to have outbreaks just not one big one.
