I get those bumps on my scalp too. My doctor told me to use Denerex shampoo. Occasionally I will pour witch hazel on my scalp to soak up oils and ease inflammation.
He's never told me what's causing them, but the treatment seems to keep it mostly under control.

Did your doctor check your hands for early signs of RA? My hands started making popping and crackling sounds along with swelling. My rheumatologist xrayed my hands and discovered early RA.
