Doctor, I've been getting these headaches which begin as a deep pain behind my eye. They go from my eye to my jaw and specific points of pain are jaw, base of skull, top of skull, behind ear, where shoulder meets neck. When I have such a headache I am very dizzy, technically it's vertigo. After the ache has begun my nostril slowly closes itself and adds a bit to the pressure, but I've had sinus headaches and this is different. Something in my head seems to be swelling and blocking the nasal passage rather than the nasal passage being blocked and causing the pain. I can also have a completely clear nose and still have the headache. There is a strange flexing sensation I get in my head near my nose that alleviates the pain for half a second. It flexes when I turn my head a certain way or if I'm in the extreme cold. Can you give me any clues as to what may be going on? I should tell you I have been having MS symptoms, but not diagnosed as having MS. I am diagnosed with endometriosis and it causes, or the MS causes, disabling pain.
