Hello,
I am experiencing something similar to what both of you describe. It is a sharp shooting pain which often starts to appear around my eye and moves to the back of my head until the pain is present in my entire head. If I don't move my head the pain seems to stabilize, but whenever I move my head quickly it is like a shooting pain which makes me feel like my whole brain is going to explode.
I have some other observations:
1. For me it is directly related to changes in Barometric Pressure. It tends to happen particularly if the pressure drops rapidly during the passage of a warm weather front during an increase in humidity. These are the same conditions that lead to rain.
Within the last day the pressure dropped, the humidity rose 40%, and the temperature peaked and is once again dropping. Note that the temperature is approaching the dewpoint (before the rain).
I have it right now, check out the weather conditions:
Data as of: 10:30 PM
* Wind Chill: 19°C
* Humidity: 82%
* Dew Point: 16°C
* Avg Wind: 7 N
* Pressure: 1012.87mbar
2. The headache disappears during/after the rain.
3. The things that help me are:
- drinking massive amounts of coffee
- head massages
- naps
- showers
- more coffee, with sugar!!!
According to one scientific study lead by Dr. Galina Mindlin at the Jefferson Medical College in Philadelphia on this subject, there was a definite correlation established between chronic sufferers of headaches and changes in weather patterns.
Other studies as far back as 1981 have confirmed this phenomenon.
Hope this helps!
Daniel
