question: Hi, I have a small purple dot between my molar and tonsil , basically beside the back of my tongue . It s very uncomfortable. It feels like a swollen tonsil. The pain comes and goes. The only explanation I found online was oral cancer , as I am a smoker, female and 26 yrs old. I am planning on making an appointment with my doctor but just to relieve some stress ( since I suffer from anxiety ) I was wondering if there could be another reason this is going on. Nothing got stuck back there and I rarely ever cough. Thank you in advance.
