I have recently had a blood patch for a continous head ache which was believed to be caused by low cerebral fluid pressure. The head ache continues and feels like a bruise below the skull behind left ear. Location of the leak has not been identified. I did have a fall about 3 years ago in which I hit my head. I had tingling and numbness around my eye after the fall. I continue to have the numbness, but also now have pain. About 5 months after the fall was the first sypmtoms of a severe headache and I went to the emergency room. (I had been complaining of 'sinus pressure' and pain before that). It has been three years of trying to deal with it. I was diagnosed with Breast cancer in 2010 and a happy side effect of the treatments for cancer was that the headache disappeared for several months. It came back with a vengence in December 2011 and at that point was diagnosed as possible CFS leak and I recently had a blood patch. The head ache persists, although it is less severe right now. Does anyone out there have similar continuous headaches that get better when you lay down and increase when up or later in the day?
