I had found tiny small red dots on front of my tongue which are not gone away even after 25 days and some times they hurts, in past I had used tobacco products for roughly 6 years, now from last 3 days I found bumps on back of my tongue and side back of tongue which hurts when touched to teeth, I recently consult a doctor who give me multivitamin tablets and 2 mouth paste tubes but after taking those medicines the bumps I think more hurts. I am very scared about it, I read some articles about symptoms of mouth cancer on internet which really stressed me, I didn't understand what to do, please help me if anyone can tell me about that.
