Hi and thank you so much for this query. I am sorry to hear about this head injury that you sustained. Because you are able to ask this question yourself and narrate exactly what happened, I am confident that you did not sustain a serious brain injury. You might have suffered a brain concussion. Rest and tylenol would provide some help to you. should anything abnormal like severe headaches, poor memory, excessive sleepiness set in, please seek further medical attention. I hope this helps. I wish you well. Feel free to ask for more information and clarifications if need be. Thank you so much for using our services, we very much appreciate this.
