I am 23 years old male. While sitting on a chair, I was resting my head on my right hand fist, because I was feeling sleepy. I did fall asleep, and that made my head slide down the fist and mid air. I woke up immediately. But I feel like I punched my right side of the head. But I have an immense fear of head injury. I did not fall off my chair. It was just a brief moment of falling asleep and waking up as soon as I did. But i am just anxietic about me getting hit by my own hand idk. Please help me out in knowing can such injury cause any trauma to the brain? PS: I DO HAVE ANXIETY DISORDER. But I wanna make sure i am totally fine. Please In the past I did fall off the bed but the reports turned out normal with no internal injury neither external. But i am just too worried about getting hit in the head and get either a very bad concussion or internal bleeding.
