For 4 solid months, I get a headache
when I move quickly, constrict my abdominal area, sneeze, blow my nose, turn over in bed, etc. It started as a constant, low grade headache, and has gradually morphed into a reaction to these movements. It feels related to something vascular and subsides once the pressure evens out in my head. I've ruled out all things life threatening with a CT scan, MRI and MRV. I've been to a neurologist, cardiologist, and physical therapist.
