How are you? Are there other symptoms present? Exertion headaches present with generalized head pain of short duration during or following physical exertion (running, jumping, or sexual intercourse), or passive exertion. Majority of this type of headache are related to migraine or cluster headaches. However, the cause must be accurately determined by your doctor. Your medical history and direct clinical examination are important. Take care and do keep us posted with your doctor's appointment.
