<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a lump on the roof of my mouth the dentist had told me at one time, that I must have had it since I was a child it is starting to bother me about a mouth ago. It feels like sand paper was rub on it and now all I feel is rawness, my sinuses are bothering me also, can this be connected? My ears feel stuffy and slightly burning and my throat feels like cotton is stuck in it. Please let me know what you think. I will also book an appointment with my Doctor. Thank you and God bless. Joyce  <response>: Hello have read your query. Lumps or growths on the roof of your mouth are often benign and easily treated but sometimes can indicate a more serious condition. Lump on the floor of mouth can be due to few conditions like:Torus PalatinusOral Cancermucoceleyou have not mentioned your age. Do you have any oral habit of smoking or intake of alcohol? Sinusitis is inflammation of the air cavities within the passages of the nose. Sinusitis can be caused by infection, but also can be caused by allergies. Symptoms include sore throat, headache, ear pain, fever, cough.i dont think the lump in your mouth is connected to your sinus problem.i would suggest you to visit a dentist and a physician for sinusitis. Hope this ans helpsRegards
