Can having a migraine cause high blood pressure?
A Migraine can cause blood pressure to be elevated during the Migraine attack but not at other times.
If you're experiencing spikes in blood pressure during Migraines, it's important to discuss it with your doctor. Some of the medications we take to stop Migraines shouldn't be taken with high blood pressure, so they may or may not be safe for you. Also, if your blood pressure rises too much during a Migraine, it can be dangerous, so you and your doctor will need to address what to do to get it back down.
When I've gone in w/a migraine, my blood pressure has been higher, but healthy.
