I took clindamycin for an infection in my nose. The infection went away. However on the last 2 days of the medicine I noticed I was getting a sore throat. Now I have multiple white sores in the back of my throat. I finished the medicine on Sunday. The sores are red and white in the middle and in the roof of my mouth. I think its thrush so I have been eating yogurt, I started with the yogurt for breakfast, did the apple cider vinegar before I had lunch then ate dinner and did a salt water gargle. Should I try a cup of yogurt or what...am probably going to the dr tomorrow to rule out strep.
