Hi! Good afternoon. I am Dr Shareef answering your query. If I were your doctor, I would examine the lump physically to see if it was originating from the clavicle itself, or it was a lump just adjacent to the clavicle. In the second case , it could be a lymph node swelling common in the cervical region and there has to be a primary focus of some infection or pathology for the lymph node to enlarge. So a detailed physical examination would be needed before deciding on the plan of management. Therefore, I would advise you to please take an appointment for a general surgeon in your area and get it assessed by him. Till then you could go for an anti inflammtory drug along with a proton pump inhibitor for a symptomatic relief. 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. I wish you an early recovery. Dr Shareef.
