About 2 months back, a small white scar was formed in middle of my tongue. After waiting for couple of weeks, one day suddenly I used my finger nail and wiped it off. From that point onwards, its become aggresive. It grows a bit (painful, white patches) around. I went to my dentist. She advised me Zytee gel, along with some B-Complex tab. Which I applied for around 1and1/2 months. things sometimes gets mitigated, but again grows up.
Please advise what should I do now.
