Have a severe headache that goes up my neck to crown of head. hurts if breathe or move too quickly... not migraine or sinus. any ideas?

ER?: If its a severe headache in that location unlike any others you've ever had before you probably want to head to the er. Aneurysm ruptures can cause sudden severe headaches.

SEE your doctor: Can't diagnose symptoms without seeing the patient, it could be a simple cold or a brain tumor. If you don't get better with over the counter influenza medication within a few days you should see your doctor.
