Wow, I just read one of the entries about antibiotics and remember back about when my burning mouth started, I was put on an antibiotic called Levequin. I was told it was a very strong one. I had already been ill for about 6 weeks and had been on the z-pac twice... Now I wonder if that had anything to do with this condition. I also had just had a crown replaced. Has anyone had the Levequin?
