D.P.
have you tried the throat sprays like Chloraseptic? Salt water gargling WILL help--just keep at it, like very hour. You could also try a small amt. of hydrogen peroxide in water. (1/10th peroxide to 9/10 water). It may fizzle and gag you but it will help, too.
There is a scientific reason that saltwater draws infection out--so don't give up!
Warm tea with honey? Can you manage that with sipping?
Strep throat is miserable and I hope you're feeling better soon.
Rest, rest and more rest!
