Occasionally when I yawn there is a sharp pain just below my Chin. It feels like my jaw gets locked and there is a lump that I can feel sticking out just below my chin.  It lasts a few seconds to a minute then goes away. Im wondering why this happens to me.
Hi ! Good morning. I am Chat Doctor answering your query. If I were your treating doctor, I would examine you clinically to reach at provisional diagnosis. If a lymph node inflammation is suspected, I would prescribe you a broad spectrum antibiotic and some anti-inflammatory Chat Doctor.  If it does not subside, I would advise you for a fine needle aspiration cytology/core biopsy depending on the clinical nature of the lump at that time. Apart from this, all the routine blood examination including your thyroid status have to be confirmed. However, before embarking on any kind of management plan, you have to be clinically examined by your family physician/general surgeon/ENT specialist to arrive at a provisional diagnosis. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor.
