What causes a lump on the jaw bone?
Patient: Hi, I have a pea size lump on my jaw bone, just by the corner.  It was at first bigger and painful, inflamed, and as I am pregnant I assumed it was hormonal.  Now it has shrunk in size and is no longer painful but will not go.  It does not move around but is not attached to the jaw bone.  I am 31, 5 months pregnant.  5ft 1 normal weight for height and pregnancy Doctor: Hi, dearI have gone through your question. I can understand your concern. You may have either enlarged lymphnode due to reactive hyperplasia or submandibular salivary gland enlargement.  You should go for fine needle aspiration cytology.  It will give you exact diagnosis. 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 health care magic. Wish you a very good health.
