I take preventer (Symbicort) twice a day and also have Ventolin occasionally. Recently I've managed to burn my mouth a couple of times, leaving an ulcer which takes a while to heal, and my tongue seems less sensitive. I know that with steroid skin creams you have to be careful to apply only to the affected area as it can thin healthy tissue , could this be the same with steroid inhalers ? I normally rinse my mouth or brush teeth after taking it. I have a review appointment on Monday and wondered if I should mention it.
