[|Human|] Hi doctor.First of all, I will go tomorrow to the doctor. Im 23.Ive seen today i have a black spot inside my mouth, after some days having a sort of infection, yesterday i had nothing there, its placed in my cheeck. The infection could be caused for my alergy and it looks like amisgalitis, and around i can see blue and red vains.what could it be? I smoked only for 1-3 months in my whole life, recently.Thanks.
[|AI|]  Howell come to ChatDoctorI really appreciate your concern, black spot inside the mouth (Oral cavity) is very uncommon or not likely if this is so then this could be due to some injury may be collection of blood "submucosal hematoma" this may not be infection, if this is not painful or burning then this may not be due to any pathological changes , still clinical examination is the best way to confirm the diagnosis, hope this information helps, take care.
