[|Human|] I have a lump on my head, resulting from an accident that happened a month ago.  My black eye and cuts have healed, but the lump is still there.  I went to the emergency room at the time of the injury, and I was told that the injuries should resolve.  I followed up with an urgent care physician a week ago.  She said the lump appeared to her alot like a cyst (but it was not there before running into metal street sign.)  She advised to get a sonogram.  The lump is located on my forehead above the eye.  It doesnt really hurt.  But I do have some headaches -- not severe.  Could I be referred to a doctor for a sonogram regarding this?
[|AI|]  Hi ! Good afternoon. I am Chat Doctor answering your query. Although a physical examination would be more appropriate, with your history of trauma alone, and the lesion appearing only after the trauma, it seems to me that it was a hematoma which has organized now. To confirm, a FNAC (fine needle aspiration cytology) could be done. To me, it seems that a FNAC would be more helpful in diagnosing the lesion than an ultrasound. However, as I told earlier, a physical examination would decide on the investigation required. The management would depend on these factors. 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.
