Nah .. the yellow means its been a couple days since the bruises came. And the blood in your mucus its from a small blood vessel in your nasal cavity. Its just taking a bit to get to the surface.
Unless you took a shit kicking and got good kicks in the ribs and shit and/or a hard knock on the head ...your fine.
Unless you feel fucked up dizzy and faint like. Or hear major cracking from bones. No real reason to see anyone.
