By definition, chronic daily headaches must occur 15 days or more a month, for at least three months. And to be considered true (primary) chronic daily headaches, they must also not be the result of another condition. Chronic daily headaches are classified by how long they last — more than four hours or less than four hours. The longer lasting headaches are more common and addressed here. They're divided into four types: Chronic migraine Chronic tension-type headache New daily persistent headache Hemicrania continua
Well! If something isn’t shown of on ct scan so it probably due to tension/stress the common cause of headache in today’s world nd nothing to b worry about something serious
Thank you so much for this information, My sister suffers from serious headaches every 3 or 4 days from last 2 3 years. She has been properly checked by doctors through different x rays and Even CT scan also but there is nothing wrong. Her eyesight is also checked recently which was very much weak but after wearing glasses she suffers the same headaches. She has been taking Ibrufen DS for the cure. I’m concerned about Ibrufen because it can weaken the immune system.
