Chronis hematomo

[Superz23]

I hit my head on two fridays ago. Was leaned over a trash can stood up real fast smacked top back part of mt head where curve starts on bottom of cabnet.Urgent care doctor said mild concussion.?
Headachs and all have seem to stop other then my sinues hurt and theres still some pressure in my head but i think all thats from the sinues. At the time of the incident i didnt lose conciness or black out or throw up. Like i said i went to urgent care 8 hours later he checked me out and said mild concussion. I havent been sleeping all that much maybe 5 hours or less at night. But i feel like my vision has changed and now im worried about a Chronic Subdural Hematoma. What are the number one signs for that? Is vision being messed up on of the first signs or is maybe the sleep or even the sines what are signs of chronic hematomo? Im so afraid of dieing in my sleep or going blind.
