Cluster Headache Symptoms
The pain of cluster headache is its defining and most dramatic feature. This pain comes on without warning (no forewarning symptoms such as the aura in classic migraine) and may begin as a burning sensation on the side of your nose or deep in your eye.
In addition to its one-sidedness, other characteristics separate cluster headaches from other headaches.
- The headaches commonly come on just after you go to sleep.
- Often the eye on your affected side will tear.
- Your eyelid on the affected side will droop.
- You will experience one-sided nasal stuffiness and runny nose.
- Cluster headaches have seasonal variations. Most attacks occur in January and July, where the days are in turn the shortest and longest.
