Hi Lynne, thanks for asking. You have a good observation because change in the atmosphere pressure is one of the known triggers for the onset of migraine headaches
. Some people mention that they experience an episode of migraine whenever it rains. It is not dangerous, and it should be treated regularly with a medication like Propranolol
, etc if the frequency of the headaches is more than 3 per month (at least in some seasons which you experience more headaches). If the frequency is less than 3 a month you may use just a medication like Sumatriptan
at the time a headache is starting. I wish you have a good health.
