I've had several hits to the head that weren't so serious but, recently i've been over sleeping too much and still be tired,painful headaches,slurred speech and behind my left ear i have a bump that i didn't even notice.When i got hit on the head i remember a watery yellow like fluid coming down from my nose but i didn't take it so serious and i didn't go to the hospital could my past injuries have to do with it?
