Hi, I am an 18 year old, I have Myopia and I have had the same power since the last 8 months, wearing correct spectacles, and I had a pilonidal sinus surgery in march 2010 and I had spondylolisthesis in 2006. Since the past one week, I have been having these weird headaches at the back of my head ( just above the neck) and the head aches with every pulse, whenever my heartrate goes up ( if I climb stairs or otherwise) I feel my pulse at the back of my head and pain with it, and the pain slowly decreases with the heartrate going down. I checked my BP today, its 119/68 and Today I've had a very heave head and feels as if its going to explode. My resting pulse is 102 and right now I have a mild fever of 99.5. Please help ?
