I'm sorry that I'm posting about this again. I'm having a bad night and I'm afraid that I'm spiraling downwards. I was feeling really good but I'm obsessing over this mouth sore. I thought it was a canker sore the pain is gone but the sore is still really visible. I don't understand why the pain is gone but the sore us still there it's been almost 3 weeks! Should I go to the doctor? I don't know what to do. I'm so afraid it's oral cancer. I hate that I can't be normal and know what I should do. I'm in tears please respond.
