Uvula has sore on it. Almost like a canker sore. When to quick care and tested negative for strep or bacteria. I have been gargling with salt water, has helped and the sore is beginning to heal. My tonsils are also swollen and the lymph nodes in my neck remain sore. I tend to get tonsilitus when the weather changes, this winter in Ohio been up and down. Stress causes a weakened immune and then I get this. I just have never had a spot on the Uvula before. The doc did prescribe augmentin. Is there anything I should be concerned about with this?
