[|AI|]  Hi, Thanks for writing in. It is possible that you had a scalp injury when you hurt your head. This can cause irritation of nerve endings which can get sensitized when brushing your hair. If you experience symptoms like persistent headaches, heaviness, vomiting, dizziness, loss of gait then please get back to your doctor at once for a CT scan brain to know if there is any injury to brain which is not visible from outside. Also check your scalp for any bruises and injury and signs of inflammation and infection in the scalp that might have appeared after the injury. If present you must apply antibiotic ointment containing sodium fumigate to the area. This will prevent infection.
