Hi! Good morning. I am Dr Shareef answering your query. Even though you need to be assessed clinically in person by a doctor in your place, from the history it seems to me that you have developed a
hematoma (localised collection of blood) in the back of your head under your
scalp. If you leave alone, I would advise you to go to the nearest ER and get yourself assessed. If you are having companion, then they should observe you for any change in the level of your consciousness, or change in behaviour, or any increase in the size of hematoma, and in that case, they shoud immediately take you to the nearest ER in your region.
For the present, you could go for an anti inflammatory along with a
proton pump inhibitor drug for a symptomatic relief, and put a pressure bandage over the hematoma. In uncomplicated cases, this hematoma should subsde of its own in about two weeks time.
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.
