I wanted to ask a similar question. Every year I used to get my headaches right at the peak of Fall season. Particularly when trees have shed and when their leaves start to rustle with the dry and cold wind. I noticed that over the years my cycle was delayed by 2 weeks. So 8 years ago it was around November and this year it was in January just before Spring.
However, for the first time that I can recall, my cycle started at the end of November And the headache is on the opposite side of my head. I assume it was triggered by a Nasal Spray that I used to relieve my stuffy nose for a good night sleep that turned into a nightmare.
So is it normal? For the side of headache and season to change? Should I be expecting another cycle on the other side later in the peak of Fall season? It totally got me off-guard this year as I was planning to bust once before December, that's when I was expecting it. How long will this cycle last, considering other people that have episodic cycles start around this time of the year?
Thanks guys.
