I was wondering if anyone could tell me if high blood pressure can cause chronic night time headaches? My husband gets terrible headaches as soon as he lies down to relax and watch tv, every night. This is when his blood pressure is at his highest. They are very painful and it takes a combination of advil and tylenol to take them away. It't way too many pills. He has been to an ENT, Nothing wrong there. also had a MRI. Nothing wrong there. Any help would be appreciated. Thank you
