Hi ! Good evening. I am Dr Shareef answering your query. The lump on your eyebrow would possibly be due to a collection of small amount of oozed blood due to the blunt trauma, and this collection being known as a hematoma. Usually this lump would subside of its own may be gradually as the blood gets absorbed of its own in due course of time. An anti inflammatory drug along with a proton pump inhibitor would give you a symptomatic relief of your pain. A frequent ice pack for two to three days might be helpful. If the swelling increase, or any other problem like excessive sleep or vomiting occurs, then you might have to get yourself assessed clinically at the ER of the nearest hospital. 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.
