I got a mild concussion exactly a week ago today. i noticed blood in my stool yesterday and just swept it under the rug. it happened again today and there was about half of it red blood and lots more on the paper. when i got the concussion i was very light headed and had zoned out, then fell. i’m not sure if the bleeding had something to do with falling or not. since i’ve fell ive stayed very lighted headed, hard to focus, and horrible headache. should i be worried??
