Residual skin discoloration in the groin may persist for weeks to months after more severe forms of jock itch clear. This darkish discoloration is called hyperpigmentation and may be treated with one or a combination of: Hydroquinone 4% cream. Kojic acid cream. Azelaic acid 15% cream.
In brief: Depends on severity. A tiny pimple or pustule on the skin, caused by regular staph, should heal up in 3-5 days after the pus comes out. A deeper abscess may take 1 week of treatment to clear up, and another week for the remaining wound to heal. People who have internal abscesses in their bodies, or have suppressed immune systems, can take several weeks of treatment with IV antibiotics (even longer in bone infections).
