I had a sore throat for about a week before I decided to take a look in my throat to see what the heck was causing the pain and I saw swollen tonsils and white spots all over my throat. I immediately thought strep throat, went to the doctor the same day and she told me it was strep, no swab needed to confirm because it was so swollen and white. I was given a ten day prescription of clindamycin (an antibiotic) for the infection. It's been about 72 hours since I started the antibiotic and there's no signs of recovery. In fact the white spots are growing. Is this the infection drawing out of my throat? Or are the antibiotics ineffective and it's continuing to get worse?
