Suddenly my tongue has become sensitive to normal spicy food, it's been over 20 days but it's not getting cured. Have not taken any medications till now. I smoke, but in the last few weeks I've restricted to one or 0 per day. After eating spicy food, some white patches appear on the tongue and goes away within minutes, I feel no spice after it. Mouth opening is normal, few white patches in the inner cheeks.
