My son was diagnosed with strep on Wednesday and I went and had a culture Saturday, it was negative. They grew it and I called for the results today- still negative. I would have bet you a weeks paycheck (my husband's check even!) that I had strep too. I'm miserable. Sore throat, headache, swollen glands that hurt to the touch, my neck is stiff. They said, "probably a virus" I hate that answer.
