The injection itself releases some of the pressure, and the cortisone acts as an anti-inflammatory so it turns off the neutrophils and flattens the papule.
This neutrophilic accumulation causes a small papule, or pimple.
According to WIkipedia a "nodule" can be: "a small knobbly rock or mineral cluster, such as a manganese nodule; a small aggregation of cells; a lesion similar to a papule; or Root nodule, an outgrowth formed on the roots of legumes that house symbiotic bacteria that fix atmospheric nitrogen and provide it to the plant in exchange for carbon."
The rash is peculiar to itself, not usually mistaken for anything else, being a purplish red, slightly elevated, flattened papule, about the size of a split pea.
It may appear as an erosion or as a dry scaling and indurated papule, varying in size from a pin-head to a silver dollar.
-- Nothing is noticed until the third or fourth day, when a red papule appears.
The secondary stage commences about a fortnight after the papule has healed.
The papule then develops into nodules of cylindric shape, with a dome-shaped, thick, yellow crust.
The primary stage begins with the initial lesion, which consists of a papule which may be found most anywhere on the body.
By the seventh day the apex of the papule is of a pale yellow color, and the black skin has the appearance of being dotted over with yellow wax.
