Hi, I had gone through your question and understand your concerns. You need medical and brain imaging evaluation in order to check for/ rule out any traumatic brain injury. Most probably cause of your symptoms could be Subdural hematoma, a condition when blood after a brain trauma growths slowly between brain and its covering. This condition needs prompt medical attention, so I suggest you to consult your primary care Doctor and discuss your concerns. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
