I have at the back of my throat a small white protrusion from the skin. I recently had a tooth removed and was placed on Clavulox antibiotics after getting dry socket infection. Since this my throat & uvula has become very red & swolen. The pallette appears to have a slightly yellow colour and it does not appear to be getting any better. I still had an unused supply of clavulox I have just started on after 2-3 weeks of these symptoms. I have tried warm salt water gargle and betadine mouthwash but have not had any noticeable change
