Tongue spots

I have been getting small white spots on my tongue for about a month now. At first it is a small white spot that over a a few days gets larger. it seems to get larger as the days go by. I always get it in the same spot and it goes away after about a week. It seems to come back within a two week period. i not sure what to do or if i have an disease. Also as the spot gets bigger, it turns red in the middle. I do have asthma and use an inhaler but this has never happened to me before. what do i do and what could this be? please help
