Thanks for yor query.
It seems that you have suffered from soft tissue injury
and the bleeding is a result from a cut on your skin.
I would suggest that you should get a scan of your head done to rule out any internal bleeding
Headache after head injury
can persist for few days.
Proper rest will help to decrease your symptoms.
If you are having severe pain
, you can take pain killer like Ibuprofen
one tablet twice a day after meals along with an antacid after getting yourself examined by your doctor.
Also get your wound dressed at the Emergency Department.
I hope this is helpful to you.
