Hello! I read carefully your question and understand your concern. Your symptoms may be related to tension type headache or to a lesion caused by the trauma. I would like to know if you have any other symptoms like blurring vision or eye redness. I recommend you to consult with a neurologist for a careful physical examination and perform a brain CT scan with contrast to exclude a possible post traumatic carotido-ophtalmic fistula. An ophthalmologic consult would be helpful to exclude any eye lesions. Hope to have been helpful! Greetings! Dr. Aida
