Sore throat that won't go away?

[Bshell16]

I've had a sore throat for about 3 weeks now. I originally went to the doctor with overall feeling of malaise, headache, fever, slight sore throat and abdominal pain. I was tested for strep and mono. Strep came back positive (Strep C) and negative for mono. I was prescribed amoxicillin and was feeling much better on day 3 until I developed a horrible yeast infection. I was then prescribed the one dose of fluconazole and the yeast infection was cleared. My original symptoms were gone so I didn't bother taking the rest of the antibiotic. (I know, my fault). Now three days I went back to the doctor and explained my symptoms and that I didn't finish the amoxicillin. I was not tested again for strep but was given cefdinir. I realize I am only day 3 but my throat hurts worse than it did to begin with. I'm having trouble swallowing and have a consistent stabbing pain in my throat. I'm curious if anyone else has had similar symptoms or knows if this could be a continuation of strep or something else. Thanks in advance
