About two weeks ago I had strep throat, I was given an antibiotic and took for five days. A week went by and I felt fine. Now the back of my tongue is sore, was sore on right side for three days and now the right side feels fine but it hurts on the left side. It also hurts to swallow. I feel a little nauseous. It definitely feels like the pain is more in my tongue. It feels different than when I had strep. Also, my tongue feels a little tingly.
