I'm quite concerned right now last weekend me and my friends were messing around and I was thrown head first into a wall the day after I felt fine now I'm feeling some symptoms I developed a bump on the spot i hit but along with close examination of this me and my father realize I have odd unevenness and bumps on the back of my head away from the spot I made impact Im having head pain on the left side of my head while the main painful bump lies on the right side I have also noticed before this hit to the head I have had increased stress and anxiety (a lot of worrying) I just don't know what to do and I'm looking for someone to point me in the right direction
