<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a blocked salivary gland, probably submandibular, on floor of my mouth, behind tongue to left. Ultrasound and x rays did not show a stone and there is no pain but this lump, the size of a small pea has been with me since late August and I am very worried. I am female and aged 51.  <response>: Hi, dear I have gone through your question. I can understand your concern. You may have siledinitis or some tumor of salivary gland. You should take a course of antibiotics. If it doesnt respond to treatment then you should go for fine needle aspiration cytology or biopsy of lump. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
