Hi ! Good afternoon. I am Dr Shareef answering your query. From your history, I feel that possibly you have got a lymph node inflamed in your neck region, which could be due to any infection in the drainage area of the lymph node. If I were your doctor, I would do a general physical examination of yours with special attention to your head and neck region along with the oral cavity, and would consider advising you for a short course of broad spectrum antibiotic along with an anti inflammatory drug. This might resolve the problem.Otherwise I would consider referring you to a general surgeon/ENT surgeon, who might advise you for an FNAC(fine needle aspiration cytology)/excision biopsy of the lesion to arrive at a definitive diagnosis for appropriate management of your problem. 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 health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
