Today I tried a frontflip and landed on the top part of my back/neck. Everything feels fine, I can take deep breaths and such, but if I cough I cough up a mix of blood and mucus. I got a slight headache, but that was there before I had crashed hard. My pupils are not dilated and no, I didn't bite my tongue.
Its not like my airway is constantly filling with blood, but if I try I can definitely hack some blood out.
Because everything feels fine besides the headache, should I just chill?
