I have had what looks like leukoplakia on my tongue for more than a month. I visited my doctor. He diagnosed it as bacterial and gave me a course of antibiotics. But it hasn t cleared up. I took it despite being 2 months pregnant. But I am getting worried now because its still there, I have a heavy feeling on my chest and I am starting to experience hoarseness. Please advise. I am worried!
