I had a cold about three weeks ago and noticed that my nose was hard and very dry, so after waiting to see if it went away, I went to the doctor and it turned out I had an infection in my nose. The doctor gave me an antibiotic and now my nose is fine. However, the first night I took the antibiotic I suddenly had raised bumps on the very back of my tongue. They are painless, but feel slightly uncomfortable because I can feel them when I go to swallow. I wasn't sure if this is an enlarged circumvallate papillae? What can you do to treat that?
