I think I replied to one of your earlier messages about headaches and sensitivity to light....anyway, check up on that. There is some evidence that migraines (not exactly the same as just headache) are much more common in females than males, and that they can occur as part of the female cycle. They are also linked (in some cases) to hypotension, bad diet, poor sleep patterns, sensory overload, and environmental cues. Anxiety and stress can also induce headaches.
Does any of this sound familiar to you?
If in doubt go to your GP / medical practitioner and ask to see a migraine / headache specialist (typically a neurologist) who can talk in depth about your symptoms and will get a better feel for things. This is the best place to start.
