How long does it take for strep throat to cause really bad harm?

A doctor has provided 1 answer

Variable issue: The kidney injury triggered by some strains may begin within a few weeks of an untreated strep throat. The rheumatic fever, heart & nervous system injuries may be delayed for a month or so. Effective treatment initiated within 9-10 days of first symptoms can usually stop delayed effects.The kidney issues can sometimes appear even with treatment.
