Have had a general lurg for about a week (heavy head cold, sore throat, headache, unable to breathe, ears blocked yadda yadda). Today I could feel something at the back of my mouth when I swallow, and on examination in a mirror (not easy, btw) I can see that I have a largish ulcer on the roof of my mouth at the back on the soft palate. My throat is sore, but no more than it has been iyswim. Do you reckon I need to go and get antibiotics, or is it likely to just be a virus type thing? Never had the ulcer bit before, you see.
