Hello! I am suffering of OCD, and 3 weeks ago I had a playful wrestling match with a friend at home in a room where there are some large, immovable wardrobes. We made the rules such as anyone touching one of the wardrobes during the wrestling would mean that we break off and start again, away from them, to avoid hitting and injuring each other on them. So during the fight I accidentally hit his head with my elbow (which bruised both his head and my elbow), and he also hit my ear with his head which made it hurt for several days after. The first time he took me down (which was the only time I fell), and the second time (after about 20mins of wrestling after the first time) I took him down. Now, because of my OCD I worry that I might have hit my head on one of those wardrobes when I fell, and don't remember it for some reason (false memory OCD). I know it's illogical to worry about this but for OCD sufferers it can sometimes be hard to put the mind at ease. My question is this: if I did hit my head when I fell, would it be possible for such a head injury to be serious if 3 weeks after I currently have no visible symptom? Thanks for your answer!
