Past two days with weird taste in mouth, what to do?

Hard to say!: Any new supplements, pills or over the counter drugs? New food/drink or bodycare product. New cleaners, candles, aerosols, detergents? Any other symptoms, like runny nose or cough, toothache or gum swelling? Those are some of the questions I have. In sum, if none of these point out a cause and can be eliminated (like a new vitamin, perfume, cleaner, etc.) & this continues, see doc/dentist ASAP
