Refused strep test...dr prescribed antibotics anyway?

If you are coughing up mucous, a yellowish color it's very likely to be a throat infection. If not wait about 2 days then you may wish to take it if you don't get any better. Take probiotics with the antibiotics- either as a drink or supplements to help restore the good bacteria. Most of the time, in my experience, doctors prescribe antibiotics without doing the test as they can see how red or irritated your throat looks.
