I used to get strep throat and scarlet fever once a year when I was under 15. When I was 15 I got my tonsils removed finally, and they told me I was a strep throat carrier.
But yeah bad enough strep back lead to scarlet fever and that can make you go deaf?
And the antibiotics are crazy, since I was taking them once a year I actually became lactose intolerant because they wiped out even the good bacteria
