Hello doctor , I had A bad headache / migraine a few weeks ago which lasted 8 days I could not move my head with the pain and sickness feeling the pain eased a little from time to time but didn't leave my head . It started at the front went to the top and all around my head was sore . I do suffer with headaches from time to time , but never had one like this that lasted this long before . Just like to know what may have been the cause of it . Thanku
