I am sorry that you suffered the injury
. Please look if there is a visible swelling on your scalp
or if the swelling is increasing in size.
If your consciousness level is decreasing, if you develop forceful projectile vomiting
, blurring of vision and if you develop seizures, these are signs of intracranial injury. Then you need to rush to the ER.
Else, if it is a superficial scalp hematoma
, local ice packs are sufficient.
I wish you speedy recovery.
