Hi! Good morning. I am Dr Shareef answering your query. Although it needs a physical examination to arrive at any conclusion, I would presume it possibly to be a lymph node swelling or a benign cyst like a sebaceous cyst. If I were your doctor, I would initially treat it with a course of broad spectrum antibiotic and if not relieved then would consider referring you to a general surgeon who would after a clinical assessment of the lesion and neck region, might go for some investigation like a FNAC (fine needle aspiration cytology) or an excision biopsy for a definitive diagnosis and further management. 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.
