Hello! Welcome on HCM! I carefully read your question and would explain that your symptoms are related to a head concussion. You should know that you need a certain period of time to recover spontaneously and the headache may last even some months after. I would recommend avoiding alcohol intake, straining physical activity and especially a possible repeated head trauma, which could lead to severe consequences for your health. Some bed rest would be helpful. Meanwhile, I would also advise you to take acetaminophen or ibuprofen three times daily for a week or two. If the headaches do not improve, or even worsen, you should go to the ER and perform a brain CT scan, to exclude possible delayed subdural hemorrhage. Hope you will find this answer helpful! Greetings! Dr. Aida
