My Tounge Has Been Sore For The Last Few Months.

My tounge has been sore for the last few months. I was vacationing in MN from CA and noticed it started about a week after being there. At first it was sore on both sides and front. I was applying a warm green tea bag to the effected areas. It has aleveated the soreness on both sides but not the front. Seems it's the taste buds that are swollen. I've been back to CA for only 2 days now. Should I just wait and see if this goes away? (I was drinking well water on a farm in MN)
