What antibiotics combination for paronichia;3atacks in6weeks include flucoxacillin, no result ?

Surgical drainage: Bad paronychia (infections of the skin surrounding a fingernail) often don't respond to antibiotics since the bacteria that are causing it are walled off in an abcess (pus filled balloon). The definitive treatment is surgical, the affected part of the nail or cuticle needs to be opened to allow the paronychia to drain. If that does not help, a portion of the nail can be removed.
