I hit my head hard at 3 months ago at a theme park. No unconsciousness or vomiting. At the time, I was referred to the hospital and had a once over, advice for a phased return to work and later on a head scan - which raised no problems. The guidance states that the symptoms usually disappear by about 3 weeks - so am starting to worry when they are ever going to disappear. The main issue I have is memory problems, my mind literally goes blank on many occasions. It's affecting my quality of life and my work - am I am due to present at an interview in the next week and really worried that this will impact on my success. Has anyone else had this and when did it go, any reassurance would be gratefully received
