Clogged pores on arms? pic

Does anyone else get these? I'm talking about all the little red raised bumps that are closed pores. They're more on my upper shoulder than my arm. I can't touch them, because if I do they turn into actual pimples so obviously I don't want that. I already use an acne-free body scrub to exfoliate in the shower so how else can I get rid of these? I know it's not awful but it makes me self conscious when I'm wearing anything where you can see my shoulders and upper arms.
