[|Human|] I have a sore on my gums the occasionally swells with blood and puss.  It is above the farthest molar on the left side.  Above that where the gum and the cheek meet there seems to be a solid mass that is white underneath the skin.  My neck and back have been stiff and sore with a lump underneath the muscle just where my neck meets the shoulder.  Something does not seem right.  I went to the ER a month ago and was diagnosed as having a salivary gland stone.  I went to an ENT who did a procedure with wires to open up the gland, but there was no stone.  The mass that I was trying to explain is still there.  Is this very serious?
[|AI|]  Hello, I can understand your concern. The swelling you are describing can be a result of abscess formed due to infection of the lat molar tooth. As it is on the gum just above the tooth, this can be the possibility. In that case, if you go to the dentist, he/she can examine your oral cavity for such infectious tooth and can Chat Doctor. Other possibility can be presence of cyst or tumor. In that case, the swelling or part of it needs to be excised and sent to the laboratory for the diagnosis of the tumor or cyst. This process is called biopsy. It also evaluates whether the cells of the swelling are harmless (benign) or cancerous (malignant). You should consult an oral & maxillofacial surgeon for such procedure. Treatment can be advised after the results of biopsy come. I hope this information helps you. Thank you for choosing Chat Doctor. I wish you recover soon. Best,
