You folks might want to look into boosting your immune systems. Echinacea- take it no longer than 6 weeks at a time before taking a 1-2 week break- is a good start. Elderberry Extract (Sambucol or a high quality equivalent- NOT capsules which are "whole herb") has proven anti viral properties and also has shown immune boosting properties.
There are other herbs out there which also are immune boosters.... reishi mushrooms are another.
Tonsils are a sort of blood filter, which is one of the reasons doctors don't like removing them. They help keep nasty bugs from attacking more vital organs. I suspect, though, that once they get inflamed or infected, they sort of become a target on their own. Mine were removed long ago as a child, and to be honest, it didn't change much... I still had horrible sore throats and ear infections. I also had a truly horrible immune system back then, probably much of it due more to psychological issues than physical problems. But some was probably also nutritional. Not that I was neglected- I was just a very picky eater who had developed the pattern of always being sick in my first 1 1/2 in an orphanage...
Avoiding sugar- especially white sugar- might be helpful, as it tends to depress the immune system badly for a few hours after ingestion.
zinc lozenges, taken at the FIRST twinge that hints that you might be developing problems can often stop a sore throat in it's tracks. I haven't had one... literally... since I started keeping them on hand. You have to let them dissolve in your mouth slowly, don't chew them, and don't overuse them... if you need to have a lozenge in your mouth at all times, use "inactive" ones like plain Halls or something at other times. The zinc lozenges sometimes upset people's stomachs, but I haven't found it to be a problem. Zinc interferes with the replication of most of the bacteria or viruses which cause colds and sore throats.
Have you had this cultured, so you are sure it's not strep? Strep can still go into rheumatic fever, although it's less common these days because of antibiotics. It's not something to play with....
Wishing you luck in finding a solution
