I'm having constant headache from last two days. Earlier the headaches used to go away on their own, but from last two days it's constant and unbearable. Yesterday After workout, the pain was sharp at eyes with pumping headache and blackouts . I was not able to move or even open my eyes. I get too many dreams when I sleep. After waking up from sleep.. The pumping headache begins. What is my problem ? (I'm on medication for endometriosis from last 5 months)
