my wife had a fall, resulting in a swelling to the back left of her head, as well as elbow and buttock and hip. She slipped in rainy weather on some steps whilst wearing leather soles. She spent next 36 hours in bed, sleeping for much of the time. When she got up, she found that she had weakness in her leg on the opposite side to the head injury, as well as to the arm on the same side. Speech is fine. The weakness has now gone on for 5 days. No headaches after first 36 hours.
