Hi there ~
I understand your concern. If you are vomiting
blood after an accident you should undergo more monitoring if you CT was done and it was showing FTP AC, with SDH with ipsilateral temporal contusion
, left temporal EDH and nor MLS/ME. I would have you be on observation and get the SDH out with a surgery. Also a CT of your chest might throw more light into why the blood vomiting. I hope this helps with finding out what is the cause of this bloody vomit. This can be dangerous.
I hope this helps. Take care and have a lovely day!
